An alkyl perfluoroketoester of the formula
may be used in the preparation of acyl fluorides of the formula
vinyl ethers of the formula
divinyl ethers of the formula
and allyl ethers of the formula
[In these formulae n is 0 to 6, p is 0 to 7, X is CO2M, CO2R, C02H, CONH2, COF, COCI or CN, M is alkali metal, ammonium or quaternary ammonium and R is C1-8 alkyl.] Film-forming copolymers, useful as molding resins, can be derived from the vinyl ethers and a fluorinated vinyl monomer, for example, tetrafluoroethylene.
ion-exchange copolymers of the vinyl ethers and allyl ethers are useful as the membrane in a chloroalkali electrolysis cell.
