ABSTRACT OF THE DISCLOSURE A vulcanizable rubber composition comprising (1 100 parts by weight of a polymer composition comprising (I) a vinylidene fluoride resin, (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 (III) another blendable polymer, wherein the weight ratio of (I)/[(II) + (III)] is 5/95 to 60/40 and the weight ratio of (II)/(III) is 100/0 to 50/50, and (2) 0 to 40 parts by weight of a plasticizer. Said rubber composition excels not only in heat resistance, gasoline resistance and sour gasoline resistance but also in gasohol resistance and sour gasohol resistance and further is good in tensile strength, elongation and balance between gasoline resistance and low-temperature resistance. Therefore, said rubber composition can be used in the fluid-contacting surface of a diaphragm and can be suitably used as an inner tube of a fuel hose.
