Abstract
An elastomeric composition having excellent properties such as excellent heat aging characteristics, dimensional stability, processability, fabrication qualities, hydrolytic resistance, yellowing resistance, and weatherability, which comprises PA1 (A) a graft polymer of a rubbery copolymer consisting predominantly ethylene-propylene with at least two groups of the monomers selected from an aromatic vinyl compound, an ethylenically unsaturated nitrile and a methacrylic acid ester, and PA1 (B) a polymer selected from a thermoplastic polyurethane, an aromatic vinyl-conjugated diene block copolymer, a polyester elastomer and an olefinic elastomer, in the weight ratio of 10:90 to 90:10.
