Abstract
An elastic copolymer composition which contains a copolymer having a content of polymer units based on vinylidene fluoride as low as from 0.5 to 15 mol %, which is satisfactory in polyol vulcanizability and which gives a vulcanizate excellent in heat resistance and oil resistance. This composition comprises a tetrafluoroethylene (35 to 65 mol %)/propylene (20 to 50 mol %)/vinylidene fluoride (0.5 to 15 mol %) copolymer, an organic quaternary ammonium hydroxide or a salt of an organic quaternary phosphonium compound with a nitrogen-containing heterocyclic compound, an organic polyhydroxy compound, and a metal oxide or a metal hydroxide, and optionally contains an amine compound.
