Fluorinated ethylene vinyl ether.

Polymer chemistry 2011 49 9 2051 2058. Vinyl ether monomers of the formula str1 wherein n is 0 or 1 and r is ch 3 or c 2 h 5 precursors thereto and copolymers with e g tetrafluoroethylene are provided. A halogenated ether is a subcategory of a larger group of chemicals known as ethers an ether is an organic chemical that contains an ether group an oxygen atom connected to two substituted alkyl groups. What differentiates a halogenated ether from other types of ethers is the substitution halogenation of one or more hydrogen.

Synthesis and characteristics of their micelles in water fluorine containing amphiphilic block copolymers poly 2 hydroxyethyl. Anesthetic agent ethyl ether vinyl ether soda lime volatile anesthetic these keywords were added by machine and not by the authors. The homopolymerization of ethylene is known to be highly active with this catalyst in contrast to the fluorinated vinyl ether which does not homopolymerize. This process is experimental and the keywords may be updated as the learning algorithm improves.

Copolymerization of ethylene with a vinyl ether bearing a fluorinated group. Fluorinated vinyl ether homopolymers and copolymers. Journal of polymer science part a. Living cationic polymerization and temperature induced solubility transitions in various organic solvents including perfluoro solvents.

The copolymers are useful as electrical insulation and as the sheath portion of optical fibers and can be converted to known ion exchange polymers having carboxylic groups which are useful e g in the form of permionic. The copolymerization of e with fave8 led to linear poly e co fave8 statistic copolymers that were characterized by means of various techniques. Commercial examples of the latter include perfluoroalkyl vinyl ether pave such perfluoroethyl vinyl ether peve. Fluorinated ethylene propylene resins are in general copolymers of tetrafluoroethylene with hexafluoropropylene and possibly one or more other comonomers.

A good example of an ether is the solvent diethyl ether.
