PURPOSE:To provide the titled compsn. which has excellent resistance to rancid alcohol-blended gasoline and static-dynamic composite ozone resistance, consisting of a vinyl chloride resin and a specified copolymer rubber of a partially hydrogenated unsaturated nitrile with a conjugated diene. CONSTITUTION:Not less than 5wt% vinyl chloride resin is blended with a copolymer rubber of a partially hydrogenated unsaturated nitrile with a conjugated diene, such as an acrylonitrile-butadiene copolymer rubber, wherein a bonded unsaturated nitrile content is 10-70wt% and degree of hydrogenation in the conjugated diene moiety is 50-98mol%. The mixture is kneaded with heating. |
