Carbon-carbon main chain polymer with accumulated oligo(ethylene glycol)-substituted cyclotriphosphazenes: Study on the LCST-type phase separation of organic-inorganic poly(substituted methylene)s was written by Shimomoto, Hiroaki;Yamada, Tomohiro;Itoh, Tomomichi;Ihara, Eiji. And the article was included in Polymer Journal (Tokyo, Japan) in 2020.Electric Literature of C5H12O3 This article mentions the following:
The synthesis and characterization of organic-inorganic thermoresponsive poly(substituted methylene)s are described. Diazoacetates with oligo(ethylene glycol)-substituted cyclotriphosphazenes were synthesized, and the obtained products were employed as monomers for Pd-initiated polymerization to produce carbon-carbon main chain polymers bearing an oligo(ethylene glycol)-substituted cyclotriphosphazene on every main chain carbon atom. The resulting polymers with densely accumulated oligo(ethylene glycol) units around the polymer main chain showed lower critical solution temperature-type phase separation in an aqueous medium. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Electric Literature of C5H12O3).
2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Electric Literature of C5H12O3
