PURPOSE: To obtain the title composition improved in storage stability, the tensile strength of a vulcanizate, etc., by mixing a fluorine-containing elastomer with a (hydr)oxide of a bivalent metal, a polyhydroxy aromatic compound and a specified quat. ammonium salt compound in a specified mixing ratio. n CONSTITUTION: 100 pts.wt. fluorine-containing elastomer (A) (e.g., vinylidene fluoride/hexafluoropropene copolymer) is mixed with about 1-40 pts.wt. (hydr) oxide (B) of a bivalent metal (e.g., magnesium oxide), about 0.5-10 pts.wt. polyhydroxy aromatic compound (C) (e.g., bisphenol A) and about 0.1-10 pts.wt. quat. ammonium salt compound (D) of the formula (wherein R is a 1-24C alkyl, a 7-20C aralkyl, R' is piperidino or pyrrolidinyl, and X is an anion), e.g., 1- benzyl-4-piperidinopyridinium chloride, to produce a fluorine-containing elastomer composition. n COPYRIGHT: (C)1989,JPO&Japio |
