ABSTRACT:
Ketoester of the formula ##STR1## .alpha.-carboxylate-.omega.-acyl fluoride of the formula ##STR2## vinyl ether of the formula ##STR3## divinyl ether of the formula ##STR4## allyl ether of the formula ##STR5## and film-forming copolymers, useful as molding resins, of the vinyl ether and/or the divinyl ether or the allyl ether and a fluorinated vinyl monomer, for example, tetrafluoroethylene, wherein, in the above formulas, n is 0 to 6, p is 0 to 7, X is CO.sub.2 M, CO.sub.2 R, CO.sub.2 H, CONH.sub.2, COF, COCl or Cn, M is alkali metal, ammonium or quaternary ammonium and R is C.sub.1-8 alkyl, selected copolymers, after hydrolysis, being water-wettable and dyeable, exhibiting ion-exchange properties and being useful in curable fluoroelastomer compositions and, in film form, as the membrane in a chloroalkali electrolysis cell.
