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.
式中的烷基全氟酮酯
可用于制备式
式中的乙烯基醚
式中的二乙烯基醚
和式烯丙基醚
[在这些式中,n 为 0 至 6,p 为 0 至 7,X 为 CO2M、CO2R、C02H、CONH2、COF、COCI 或 CN,M 为碱金属、铵或季铵,R 为 C1-8 烷基]。可用作成型树脂的成膜共聚物可由乙烯基醚和氟化乙烯基单体(例如四氟乙烯)制成。
乙烯基醚和烯丙基醚的离子交换共聚物可用作氯碱电解槽的膜。
