Preparation, decarboxylation and polymerization of novel acid fluorides and resulting monomers

A method of polymerizing one or more of the compounds represented by the general formula

• Y(CF.sub.2).sub.a (CFR.sub.f).sub.b CFR'.sub.f --O--CF.dbd.CF.sub.2
• where
• a=0 to 3;
• b=0 to 3;
• R'.sub.f and R.sub.f are independently selected from the group consisting of F and Cl;
• and
• Y=Br;
• and at least one other compound is selected from a second group of compounds selected from the group consisting of:
• trifluoromonochloroethylene, trifluoroethylene, vinylidene fluoride, 1,1-difluoro-2,2-dichloroethylene, 1,1-difluoro-2-chlorohexafluoropropylene, 1,1,3,3-pentafluoropropylene, octafluoroisobutylene ethylene, vinyl chloride, and alkyl vinyl ether;
• said method consisting essentially of reacting at least one compound from the first group with at least one compound from the second group in the presence of an initiator for a sufficient time and a sufficient temperature to polymerize said compounds.
