Process for producing a vinylidene fluoride copolymer.

摘要

A process for producing a vinylidene fluoride copolymer, comprising the step of copolymerizing a mixture of monomers containing a polymerizable double bond comprising: (A) vinylidene fluoride, and (B) a fluorine compound represented by the formula: CH2=CH-Rf (I) wherein Rf is a perfluoroalkyl group having 1 to 12 carbon atoms, with the content of (B) being 0.1 to 50 % by weight, in the presence of a radical polymerization initiator. A vinylidene fluoride copolymer having excellent flexibility, impact resistance and cold resistance together with the good characteristics inherently possessed by polyvinylidene fluoride can be obtained.
