Abstract

PURPOSE: To provide title copolymer having improved vulcanization characteristics and compression set obtained by copolymerizing hexafluoropropene, 1,1,3,3-pentafluoroporpene and vinylidene fluoride.
CONSTITUTION: Hexafluoropropene and 3W60mol% of 1,1,3,3-penetafluoropropene based on hexafluoropropene are added to vinylidene fluoride in such a proportion that the sum of hexafluoropropene and 1,1,3,3-pentafluoropropene is 15W30mol%. The mixt. is polymerized in the presence of a polymn. initiator, such as a cpd. contg. peroxy linkage or an org. peroxide, at a temp. of 60W100°C in an aq. medium by emulsion polymn. to obtain fluorine-contg. elastomer terpolymer of vinylidene fluoride-hexafluoropropene-1,1,3,3-pentafluoropropene.
