Abstract
A dynamically vulcanized composition is provided which comprises a polyolefin resin, an elastomer, and an ethylene copolymer resin such as a copolymer of ethylene and vinyl acetate or an alkyl acrylate. A process for producing the dynamically vulcanized composition is also provided, which process includes the addition of the ethylene copolymer resin after the dynamic vulcanization step. The resulting composition comprises the ethylene copolymer resin predominantly in the polyolefin resin phase. The compositions have improved surface appearance and softness.
