ABSTRACT OF THE DISCLOSURE Blends of polyvinyl chloride and modified nitrile rubber are provided which have superior physical properties to similar blends of polyvinyl chloried and normal nitrile rubber. The modified nitrile rubber contain small amounts of tertiary amine groups, which may be incorporated by copolymerizing with the conjugated diolefin and unsaturated nitrile monomer a tertiary amine group containing monomer such as dimethylaminoethyl methacrylate. The blends can range from rigid or flexible uncured blends, of good impact strength, to rubber compositions of improved green strength, vulcanizable to yield vulcanizates of enhanced physical and abrasion properties. The rigid blends may be used in containers or pipes and the rubbery blends may be used in wire and cable jackets, hose covers and molded goods.
