Abstract
Blended polymer compositions are described which comprise PA0 (I) from about 1% to about 97% by weight of at least one alpha-olefin polymer; PA0 (II) from about 1% to about 97% by weight of at least one polyamide; PA0 (III) from about 1% to about 97% by weight of at least one polymer of a vinyl aromatic hydrocarbon; and PA0 (IV) an effective amount of a mixture of two or more compatibilizing agents selected from the group consisting of PA1 (IVa) at least one selectively hydrogenated block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene; PA1 (IVb) 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 monocarboxylic or dicarboxylic acid reagent; and PA1 (IVc) 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. The polymer blends of the present invention have improved impact-resistance.
