Abstract
Blended polymer compositions are described which comprise PA0 (I) from about 1% to about 98% by weight of at least one olefin polymer; PA0 (II) from about 1% to about 98% by weight of at least one polyamide; PA0 (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 PA0 (IV) from 0 to about 25% by weight of at least one auxiliary compatibilizing agent selected from the group consisting of PA1 (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; PA1 (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 PA1 (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 o…
