Abstract

Blended polymer compositions are described which comprise (I) from about 1% to about 98% by weight of at least one olefin polymer; (II) from about 1% to about 98% by weight of at least one polyamide; (III) an effective amount of a compatibilizing agent which comprises at least one terpolymer of an alpha-olefin, at least one acrylic ester, and an alpha,beta-olefinically unsaturated dicarboxylic acid reagent, or a glycidyl acrylate; and (IV) from 0 to about 25% by weight of at least one auxiliary compatibilizing agent selected from the group consisting of (IVa) at least one selectively hydrogenated block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene to which has been grafted, an alpha,beta-olefinically unsaturated carboxylic acid reagent; (IVb) at least one polymer which is the product of the reaction of an alpha-olefin polymer and an alpha,beta-olefinically unsaturated carboxylic acid reagent; and (IVc) a mixture of (III) and (IVa) and/or (IVb) reacted in the presence of a radical initiator provided that when the blended polymer contains one or more of the auxiliary compatibilizing agents (IVa) or (IVb), the blended polymer is free of other polymers of vinyl aromatic hydrocarbons.
