Abstract:
An impact modifier for thermoplastic polyamides consisting essentially of:(A) a maleated EP or EPDM copolymer; and(B) a maleated very low density polyethylene;the melt flow index of pure (A) is less than 0.1 g per 10 minutes at 230.degree. C. and 2.16 kg weight and the melt flow index of pure (B) is at least 20 g per 10 minutes at 230.degree. C. and 2.16 kg weight;wherein the melt flow index of the resulting composition is in the range of from about 5 to about 100 g per 10 minutes at 230.degree. C. and 2.16 kg weight under conditions wherein the melt flow index of pure (A) is less than 0.1 g per 10 minutes at 230.degree. C. and 2.16 kg weight and the melt flow index of pure (B) is at least 20 g per 10 minutes at 230.degree. C. and 2.16 kg weight.
