<p>A polymer blend contains: 1) about 1 % to about 98 % of a graft copolymer comprising a backbone of a propylene polymer material having graft polymerized thereto monomers selected from a) at least one vinyl aromatic compound and an unsaturated carboxylic acid and b) at least one vinyl aromatic compound and an anhydride of an unsaturated acid or its acid form, wherein the polymerized monomers are present in an amount of about 10 to about 95 parts per hundred parts of the propylene polymer material, and 2) about 99 % to about 2 % of at least one polyamide resin. The composition optionally also contains about 2 % to about 30 % of one or more rubber components, about 5 % to about 90 % of a broad molecular weight distribution propylene polymer material, or both.</p> |
