Vinyl ether compound, process for producing the same and copolymer containing the same

A novel bifunctional vinyl ether compound having an aromatic ring, represented by the following general formula: where X is a halogen atom and n is an integer of 1 to 5, effective as a copolymer component for fluorine-containing elastomers is produced by adding a chlorine atom or a bromine atom (Y)...

Zusammenfassung:A novel bifunctional vinyl ether compound having an aromatic ring, represented by the following general formula: where X is a halogen atom and n is an integer of 1 to 5, effective as a copolymer component for fluorine-containing elastomers is produced by adding a chlorine atom or a bromine atom (Y) to CF2=CFO(CF2)nCOOR, where R is a lower alkyl group, then subjecting the resulting CF2YCFYO(CF2)nCOOR to hydrolysis and acid chloridation, followed by reaction with monohalogenobenzene, reaction with SF4 to convert -CO- to -CF2-, and dechlorination or debromination, or by subjecting CF2=CFO (CF2)nCOOR to hydrolysis and acid chloridation, followed by reaction with monohalogenobenzene and reaction with SF, to convert -CO- to -CF2-.
