Rubber-modified nylon composition

A polymer blend consisting essentially of:

• (A) 5 to 94.5 weight percent of a core/shell graft rubber copolymer comprising from 5 to 80 weight percent of a rubber core of polybutadiene or a butadiene copolymer and from 20 to 95 weight percent of a thermoplastic copolymer shell comprising from 0 to 75 weight percent styrene, 0 to 75 weight percent polar monomer selected from the group consisting of (meth)acrylonitrile and methyl (meth)acrylate, and 1 to 25 weight percent of acrylamide,
• (B) 5 to 94.5 weight percent of a polyamide;
• and
• 0.5 to 10 weight percent of a terpolymer rubber of an .alpha.-olefin, a C.sub.1 to C.sub.4 alkyl acrylate and an acid-containing monomer, having a glass transition temperature below 0.degree. C.
