Abstract
A composition comprising a polyamide, a reinforcing amount of glass fiber, and 1 to 25, preferably 5 to 25, and more preferably 10 to 20 percent by weight based on the weight of the polyamide of a core/shell polymer. The core/shell polymer comprises 40 to 90 and preferably 50 to 90 parts by weight of an elastomer core and 10 to 60 and preferably 10 to 50 parts by weight of a rigid thermoplastic polymer shell. The shell comprises an interpolymer of 20 to 100 parts by weight of an methyacrylic ester, 0 to 80 parts by weight styrene, and from 0 to 50 parts by weight of acylonitrile. The shell can also contain alkyl acrylates, allyl methacrylates, diallyl methacrylates, and the like. The methacrylic ester is preferably a lower alkyl methacrylate/such as methyl methacrylate. The core is an elastomer and can be a diene elastomer, an ethylene-propylene-diene rubber, an acrylic elastomer, or a polyurethane elastomer.
