Vinyl ether compound, process for producing the same and copolymer

Abstract

A novel bifunctional vinyl ether compound having an aromatic ring, represented by the following general formula: ##STR1## 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 CF.sub.2 .dbd.CFO(CF.sub.2)nCOOR, where R is a lower alkyl group, then subjecting the resulting CF.sub.2 YCFYO(CF.sub.2)nCOOR to hydrolysis and acid chloridation, followed by reaction with monohalogenobenzene, reaction with SF.sub.4 to convert --CO-- to --CF.sub.2 --, and dechlorination or debromination, or by subjecting CF.sub.2 .dbd.CFO (CF.sub.2)nCOOR to hydrolysis and acid chloridation, followed by reaction with monohalogenobenzene and reaction with SF, to convert --CO-- to --CF.sub.2 --.
