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 --.
下列通式所示的含有芳香环的新型双官能团乙烯醚化合物,其中X为卤素原子,n为1至5的整数,通过将氯原子或溴原子(Y)加到CF.sub.2 .dbd.CFO(CF.sub.2)nCOOR中,其中R为低碳基团,然后对所得的CF.sub.2 YCFYO(CF.sub.2)nCOOR进行水解和酸氯化作用,随后与单卤代苯反应,与SF.sub.4 反应将--CO--转化为--CF.sub.2--,然后进行去氯化或去溴化,或者通过对CF.sub.2 .dbd.CFO(CF.sub.2)nCOOR进行水解和酸氯化作用,随后与单卤代苯反应和与SF反应将--CO--转化为--CF.sub.2--而制备,该化合物对于含氟弹性体的共聚物组分具有有效作用。
