PURPOSE:The titled composition suitable as a fuel hose of automobile, having improved gasoline resistance, sour gasoline resistance, sour gasohol resistance, etc., obtained by blending specific acrylic multiple copolymer rubber with a vinylidene fluoride resin in a specific ratio. CONSTITUTION:(A) Polyfunctional copolymer rubber consisting of A1: 30-99.9wt% acrylic acid alkyl ester (e.g., methyl acrylate, etc.) shown by the formula I (R1 is 1-18C alkyl) and/or an acrylic acid alkoxy-substituted alkyl ester (e.g., 2-methoxyethyl acrylate, etc.) shown by the formula II (R2 and R3 are 1-12C alkyl), A2: 0.1-10wt% crosslinkable monomer (e.g., diene compound, etc.), and A3: 0-70wt% ethylenic unsaturated compound (e.g., acrylonitrile, etc.) (with the proviso that A1+A2+A3=100wt%) is blended with (B) a vinylidene fluoride resin in weight ratio of 95/5-40/60.
