Abstract:
A polymer alloy formed by melt mixing a composition comprising:(A) from about 40% to about 75% by weight of at least one polyamide; (B) from about 10% to about 50% by weight polypropylene; (C) from about 0.01% to about 1.0% by weight of a block copolymer comprising a vinyl aromatic monomers and conjugated diene monomers, to which has been grafted an unsaturated dicarboxylic acid or functional derivative thereof; (D) from about 0.1% to about 5.0% by weight of (i) a block copolymer of a vinyl aromatic monomer and a conjugated diene, to which no dicarboxylic acid or functional derivative thereof has been grafted; or (ii) an EPDM terpolymer, (E) from about 0.01% to about 7.5% of a compatibilizing agent comprising the reaction product of an alpha-olefin polymer and an unsaturated dicarboxylic acid or functional derivative thereof; and (F) from about 5% to about 50% by weight of a filler.
