Hexafluoroisobutylene and its higher homologues are easily reacted with SO 3 to give the formula CH 2 ═C (R) CF 2 OSO 2 F, where R is a straight chain composed of 1 to 10 carbon atoms. , A branched, or cyclic fluoroalkyl group and may contain ether oxygen). These compounds react with many nucleophiles under mild conditions to give CH 2 ═C (R) CF 2 X, where X is derived from the nucleophile. This reaction provides a route to many substituted hexafluoroisobutylenes that readily copolymerize with other fluoro and hydrocarbon monomers such as vinylidene fluoride and ethylene. |
