ABSTRACT:
A rubber composition capable of giving a highly oil-resistant vulcanizate with an organic peroxide as the vulcanizing agent is proposed. The composition is a blend of an EPM or EPDM rubber and an acrylic rubber loaded with a reinforcing filler, of which the latter rubber is a copolymer having at least two vinylsilyl groups in a molecule as the pendant groups introduced by the copolymerization of one or more acrylic monomers with a vinylsilyl-containing organosilicon compound having an aliphatically unsaturated group copolymerizable with the acrylic monomers in a molecule, such as CH.sub.2 .dbd.CH--CO--O--CH.sub.2 CH.sub.2 CH.sub.2 --Si-- and CH.sub.2 .dbd.CH--C.sub.6 H.sub.4 --Si--. The covulcanizate has the high mechanical strengths of the EPM or EPDM rubber and the high oil resistance of the acrylic rubber in combination.
