Abstract

A vulcanizable rubber composition comprising (1) 100 parts by weight of a polymer composition comprising PA0 (I) a vinylidene fluoride resin, PA0 (II) at least one rubber selected from the group consisting of acrylic rubbers, .alpha.,.beta.-unsaturated nitrile-conjugated diene copolymer rubbers and hydrides of .alpha.,.beta.-unsaturated nitrile-conjugated diene copolymer rubbers, said acrylic rubber consisting of (A) 30 to 99.9% by weight of an alkyl acrylate and/or an alkoxy-substituted alkyl acrylate, (B) 0.1 to 10% by weight of a crosslinkable monomer and (C) 0 to 70% by weight of another ethylenically unsaturated compound copolymerizable with (A) and (B) (the sum of (A), (B) and (C) is 100% by weight) and said .alpha.,.beta.-unsaturated nitrile-conjugated diene copolymer rubber consisting of (D) 10 to 60% by weight of an .alpha.,.beta.-unsaturated nitrile, (E) 15 to 90% by weight of a conjugated diene and (F) 0 to 75% by weight of another ethylenically unsaturated compound copolymerizable with (D) and (E) (the sum of (D), (E) and (F) is 100% by weight, and PA0 (III) another blendable polymer, wherein the weight ratio of (I)/[(II)+(III)] is 5/95 to 60/40 and the weight ratio (II…
