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

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

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 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

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 December 1, 2013, Itoh, Takahito; Fujita, Katsuhito; Inoue, Kentaro; Iwama, Hiroki; Kondoh, Kensaku; Uno, Takahiro; Kubo, Masataka published an article.HPLC of Formula: 929-37-3 The title of the article was Solid polymer electrolytes based on alternating copolymers of vinyl ethers with methoxy oligo(ethyleneoxy)ethyl groups and vinylene carbonate. And the article contained the following:

Alternating copolymers (poly(1a-g-alt-VC)) of vinyl ethers with various methoxy oligo(ethyleneoxy)ethyl groups and vinylene carbonate (VC) were prepared, and the thermal and electrochem. properties of their polymer electrolytes with LiTFSI and interfacial stability between the polymer electrolyte and Li metal electrode were investigated. Tg’s increased linearly with salt contents, and decreased with an increase in the chain length of methoxy oligo(ethyleneoxy)ethyl groups in the vinyl ethers at constant salt concentration The slopes of Tg vs. [Li]/[O] were identical, independent of the polymer structure. The ionic conductivities of the polymer electrolytes increased with increasing the side-chain ethyleneoxy (EO) unit length of the vinyl ether unit in the alternating copolymers, and also their temperature dependences became relatively smaller in the polymer electrolytes having longer EO units in the vinyl ethers. The highest ionic conductivity, 1.2 × 10-4 S/cm at 30°C, was obtained in the alternating copolymer with a side-chain EO unit length of 23.5 in the vinyl ether unit. Ion transport coupled with the segmental motion of the polymer is dominant in these polymer electrolytes. Interfacial resistance increased gradually with contact time, indicative of the formation of passivation films on the Li metal electrode. These polymer electrolytes are thermally stable and have large electrochem. windows of use. The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).HPLC of Formula: 929-37-3

On May 13, 2014, Choi, U. Hyeok; Liang, Siwei; O’Reilly, Michael V.; Winey, Karen I.; Runt, James; Colby, Ralph H. published an article.Name: 2-(2-(Vinyloxy)ethoxy)ethanol The title of the article was Influence of Solvating Plasticizer on Ion Conduction of Polysiloxane Single-Ion Conductors. And the article contained the following:

Lithium ion conduction is investigated for a polysiloxane-based single-ion conductor containing weak-binding borates and cyclic carbonate side chains, plasticized with poly(ethylene glycol) (PEG). The addition of PEG increases the conductivity by up to 3 orders of magnitude compared to the host ionomer. A phys. model of electrode polarization is used to sep. ionic conductivity of the ionomers into number d. of simultaneously conducting ions and their mobility. A reduction in Tg with increasing PEG content boosts ion mobility owing to an increase in polymer chain flexibility. Further, the PEG ether oxygens lower the activation energy of simultaneously conducting ions (from 14 to 8 kJ/mol), significantly increasing conducting ion content by 100X, suggesting that ion aggregates observed in the host ionomer are solvated by PEG. This directly reflects the disappearance of an ion aggregation peak observed in X-ray scattering, and an initial large increase in static dielec. constant (εs), upon addition of PEG, suggesting that ionic aggregation is significantly reduced by a small amount of PEG. Further dilution with lower dielec. constant PEG gradually reduces εs.
