The solvent and temperature used in the Gilch synthesis of poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) were varied to achieve an improved set of reaction conditions. A range of mol. weights from 20 to 500 kg mol-1 were obtained in moderate to near-quant. yields. The best conditions for producing low mol. weight MEH-PPV (32 kg mol-1, 97% yield) was to use n-pentane as the reaction solvent at 25°C. For high mol. weight (397 kg mol-1, 65% yield), toluene at 55°C gave the best result. The photophys. properties for all MEH-PPV samples were examined and no significant variation was found between samples obtained under different polymerization conditions. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Safety of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

Iinuma, Atsushi; Hashimoto, Tamotsu; Urushisaki, Michio; Sakaguchi, Toshikazu published an article in 2016, the title of the article was Vinyl ether-based polyacetal polyols with various main-chain structures and polyurethane elastomers prepared therefrom: Synthesis, structure, and functional properties.Recommanded Product: 929-37-3 And the article contains the following content:

Novel acid degradable polyacetal polyols and polyacetal polyurethanes able to controlled acid degradation were developed. Polyacetal polyols with various main-chain structures were synthesized by polyaddition of various vinyl ethers with a hydroxyl group 4-hydroxy Bu vinyl ether (CH2=CH-O-CH2CH2CH2CH2-OH), 2-hydroxy Et vinyl ether (CH2=CH-O-CH2CH2-OH), diethylene glycol monovinyl ether (CH2=CH-O-CH2CH2OCH2CH2-OH), and cyclohexanedimethanol monovinyl ether (CH2-CH-O-CH2-C6H10-CH2-OH) with p-toluenesulfonic acid monohydrate (TSAM) as a catalyst in the presence of the corresponding diols 1,4-butanediol, ethylene glycol, diethylene glycol, and 1,4-cyclohexanedimethanol, resp. Polyacetal polyurethanes were prepared by a two-step polymerization, using the synthesized polyacetal polyols, 4,4′-diphenylmethane diisocyanate (MDI), and 1,4-butanediol (BD) as a chain extender. Depending on the main-chain structures, these polyurethanes had different glass transition temperature (from -44 to 19°) and properties such as hydrophobic or hydrophilic. Polyurethanes containing the hydrophilic main-chain exhibited the thermoresponsiveness and had the certain volume phase transition temperature (VPTT). The polyacetal polyurethanes were flexible elastomers around room temperature (∼25°) and thermally stable (Td ≥ 310°) and addnl. exhibited smooth degradation with a treatment of aqueous acid in THF at room temperature to give the corresponding raw material diols. © 2016 Wiley Periodicals, Inc.

On September 30, 2019, Aoki, Ryosuke; Yamaguchi, Ayaka; Hashimoto, Tamotsu; Urushisaki, Michio; Sakaguchi, Toshikazu; Kawabe, Kazumasa; Kondo, Keiichi; Iyo, Hirohumi published an article.COA of Formula: C6H12O3 The title of the article was Preparation of carbon fibers coated with epoxy sizing agents containing degradable acetal linkages and synthesis of carbon fiber-reinforced plastics (CFRPs) for chemical recycling. And the article contained the following:

New epoxy resins containing degradable acetal linkages were synthesized by the addition reaction of bisphenol-A (BA) and epoxy-functionalized vinyl ethers containing hydrophilic oxyethylene chains, 2-(vinyloxy)ethyl glycidyl ether (VEGE) and 2-[2-(vinyloxy)ethoxy]ethyl glycidyl ether (VEEGE). Carbon fibers were applied with the obtained degradable epoxy resin-based sizing agents (designated as BA-VEGE and BA-VEEGE) in ordinary (1.4 ∼ 2.2 wt%) or excess (6.4 ∼ 13.4 wt%) amounts Interfacial adhesion between the carbon fibers applied with the degradable epoxy resin-based sizing agents and matrix resins (bisphenol-A-type epoxy resin) was evaluated by the microdroplet method. Carbon fibers with both degradable epoxy resins as a sizing agent showed improved adhesive properties compared with the desized carbon fibers. Using the degradable sizing agent-applied carbon fibers, carbon fiber-reinforced plastics (CFRPs) were prepared by laminating prepreg sheets and heating them under pressure. The tensile properties of the CFRPs with [0]50 lay-up did not depend on the structure of the sizing agents, but the tensile strength decreased as the amount of sizing agent used increased. On the other hand, the tensile properties of the CFRPs with [0/90]12S lay-up were not dependent on the structure or volume of sizing agents used. The impact toughness of the CFRPs was evaluated by the charpy impact test. When an ordinary volume of sizing agent was applied, the CFRPs with degradable epoxy resin-based sizing agents exhibited higher levels of impact strength than the com. sizing agent-based CFRPs. However, applying an excessive volume of sizing agent to carbon fibers led to a decline in impact strength. The degradation reaction was conducted under acidic conditions by the treatment of HCl at room temperature or 70 °C. CFRPs with degradable epoxy resins as sizing agents in ordinary volumes were barely decomposed due to insufficient degradable regions in the CFRP components. However, the CFRPs applied with excess degradable sizing agents decomposed and carbon fibers were recovered. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).COA of Formula: C6H12O3

On September 12, 2022, Pesenti, Theo; Domingo-Lopez, Daniel; Gillon, Emilie; Ibrahim, Nada; Messaoudi, Samir; Imberty, Anne; Nicolas, Julien published an article.Product Details of 929-37-3 The title of the article was Degradable glycopolyester-like nanoparticles by radical ring-opening polymerization. And the article contained the following:

A small library of degradable polyester-like glycopolymers was successfully prepared by the combination of radical ring-opening copolymerization of 2-methylene-1,3-dioxepane as a cyclic ketene acetal (CKA) with vinyl ether (VE) derivatives and a Pd-catalyzed thioglycoconjugation. The resulting thioglycopolymers were formulated into self-stabilized thioglyconanoparticles, which were stable up to 4 mo and were enzymically degraded. Nanoparticles and their degradation products exhibited a good cytocompatibility on two healthy cell lines. Interactions between thioglyconanoparticles and lectins were investigated and highlighted the presence of both specific carbohydrate/lectin interactions and nonspecific hydrophobic interactions. Fluorescent thioglyconanoparticles were also prepared either by encapsulation of Nile red or by the functionalization of the polymer backbone with rhodamine B. Such nanoparticles were used to prove the cell internalization of the thioglyconanoparticles by lung adenocarcinoma (A549) cells, which underlined the great potential of P(CKA-co-VE) copolymers for biomedical applications. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Product Details of 929-37-3

On October 31, 2013, Liu, Bingxin; Lu, Xiaodan; Wang, Chunyu; Tong, Cuiyan; He, Yao; Lu, Changli published an article.Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene The title of the article was White light emission transparent polymer nanocomposites with novel poly(p-phenylene vinylene) derivatives and surface functionalized CdSe/ZnS NCs. And the article contained the following:

A series of new polymers with conjugated poly(p-phenylene vinylene) units and non-conjugated poly(p-xylylene) units containing vinyl and carboxyl groups were synthesized. The monodisperse CdSe/ZnS nanocrystals with a red light emission were prepared by using the phosphine-free precursors. A novel fluorescent polymer and 5-(2-methacryloylethyloxymethyl)-8-quinolinol were dispersed in vinyl monomers containing CdSe/ZnS NCs to successfully fabricate transparent bulk nanocomposites by in situ polymerization The 5-(2-methacryloylethyloxymethyl)-8-quinolinol mols. can be coordinated to the surface of CdSe/ZnS nanocrystals to form a metalloquinolate with green light emission at about 500 nm, while the red light emission of nanocrystals remained after the polymerization process. The efficient white light emitting polymer nanocomposites with color coordinates (0.32, 0.34) can be obtained when the weight ratio of nanocrystals to 5-(2-methacryloylethyloxymethyl)-8-quinolinol is 10:1. A charge transfer from the photoexcited metalloquinolates to the nanocrystals was observed in the system. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Quality Control of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene

On May 18, 1999, Ahn, Taek; Jang, Min Sik; Shim, Hong-Ku; Hwang, Do-Hoon; Zyung, Taehyoung published an article.Related Products of 146370-51-6 The title of the article was Blue Electroluminescent Polymers: Control of Conjugation Length by Kink Linkages and Substituents in the Poly(p-phenylenevinylene)-Related Copolymers. And the article contained the following:

Poly[o(m,p)-phenylenevinylene-alt-2-methoxy-5-(2-ethylhexyloxy)-p-phenylenevinylene], o(m,p)-PMEH-PPV, and poly[o(m,p)-phenylenevinylene-alt-2,5-bis(trimethylsilyl)-p-phenylenevinylene], o(m,p)-PBTMS-PPV, of varying effective conjugation lengths were synthesized by the well-known Wittig condensation polymerization between the appropriate diphosphonium salts and the dialdehyde monomers such as terephthaldicarboxaldehyde, isophthalaldehyde, and phthalic dicarboxaldehyde. The conjugation lengths of the polymers were controlled by substituents and kink (ortho and meta) linkages. The resulting polymers were highly soluble in common organic solvents. The synthesized polymers showed UV-visible absorbance and photoluminescence (PL) in the ranges of 330-430 nm and 440-550 nm, resp. The maximum emission peak of p-PMEH-PPV was blue shifted about 30 nm compared to that of MEH-PPV, which is due to an unsubstituted phenylene unit. In addition, o-PMEH-PPV and m-PMEH-PPV showed PL emission maximum peaks at 500 and 490 nm, resp., because ortho and meta linkage of the o(m)-PMEH-PPV reduced π-conjugation lengths. The trimethylsilyl substituent has no electron donating effect; therefore, the PL maximum of p-PBTMS-PPV was far more blue shifted (to 485 nm). Consequently, maximum PL wavelengths for o-PBTMS-PPV and m-PBTMS-PPV appeared around 470 and 440 nm, resp. A single-layer light-emitting diode device was fabricated which has a simple ITO (indium-tin oxide)/polymer/Al configuration. The threshold bias of trimethylsilyl-substituted o(m,p)-PBTMS-PPV was in the range of 8-9 V. As in the photoluminescence spectra, the dramatic change of emission color was also shown in electroluminescence spectra of p-PMEH-PPV, p-PBTMS-PPV, and o-PBTMS-PPV when the operating voltage was about 8-9 V. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Related Products of 146370-51-6

Soucek, Mark D. published an article in 2009, the title of the article was Cationic photopolymerization of epoxynorbornane linseed oils: effect of diluents.Quality Control of 2-(2-(Vinyloxy)ethoxy)ethanol And the article contains the following content:

New epoxynorbornene linseed oils (ENLO) were prepared as a function of norbornene content. The cationic photopolymerization of the ENLOs was investigated using real-time IR spectroscopy and photo-DSC. The effect of reactive diluent and non-reactive diluents on the polymerization rate was also studied. The diluents were found to decrease the viscosity of formulation and accelerate markedly the rate of polymerization of ENLO and increase their final conversion. The effected reactive diluent was compared for ENLO and epoxidized linseed oil (ELO). It was observed that the relative reactivity of oxiranes was not as important as the viscosity of the reacting system and proposed that the cationic photopolymerization of ENLO was controlled by diffusion. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Quality Control of 2-(2-(Vinyloxy)ethoxy)ethanol

The present work endeavors towards the scientific study on influence of ZnO nanoparticles on the optical characteristics of Poly [2 Methoxy (5, 2′ Ethylhexyloxy)-P-Phenylenevinylene] (MEH-PPV), a light emitting polymer. Hybrid nanocomposites of MEH-PPV were prepared by dispersing ZnO nanorods at loading concentrations of 1 weight % and 3 weight %. The structural characteristics of the hybrid composites were investigated using FTIR spectroscopy and X-ray diffraction. The UV absorption spectra and Photoluminescence emission spectra were analyzed in order to study the optical characteristics of nanocomposite. The optical constants were determined and the suitability of the composites for light emission was analyzed. The incorporation of ZnO nanorods facilitates the shift in emission wavelength and witnesses the color tuning ability and multicolor emission from the composite.

On December 6, 2000, Sangermano, Marco; Spera, Silvia; Bongiovanni, Roberta; Priola, Aldo; Busetto, Carlo published an article.Safety of 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was NMR investigation of UV-cured vinyl ether networks. And the article contained the following:

Structure of networks obtained by UV curing of triethylene-glycol divinyl ether (DVE3) and its mixtures with diethylene-glycol monovinyl ether (HDVE2) were investigated by high resolution 1H and 13C NMR spectroscopy. By working in swelled systems, signals with good resolution were obtained and were assigned to the different structures. The signals attributable to the CH3 end groups of the poly(vinyl ether) together with the CH2 and CH groups of the chain could be distinguished. The CH3 groups signal is stronger in the case of the DVE3/HDVE2 mixture as a consequence of the chain transfer reaction. Hydrolysis reactions occur in the systems giving rise to the formation of acetaldehyde and aldehydic end groups. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Safety of 2-(2-(Vinyloxy)ethoxy)ethanol
