ABSTRACT:
Tough multi-phase thermoplastic compositions consisting essentially of 55 to 99 parts by weight of a polyamide matrix and 1 to 45 parts by weight of a multiphase polymer comprising 50 to 90 parts by weight of a crosslinked elastomer core and 10 to 50 parts by weight of a rigid polymer shell comprising from about 1 to about 25 parts by weight of an interpolymerized ethylenically unsaturated carboxylic acid monomer, from about 20 to about 80 parts by weight of interpolymerized styrene, from about 0 to about 79 parts by weight of an interpolymerized C.sub.1 to C.sub.8 alkyl acrylate or methacrylate and from about 0 to about 45 parts by weight of an interpolymerized acrylonitrile. The toughened compositions are useful for making molded and extruded parts possessing impact resistance and ductility.
