ABSTRACT:
Polymeric blend of 60 to 90 parts by weight of a polyamide, e.g., polyhexamethylene adipamide or polycaprolactam, and 40 to 10 parts by weight of polyethylene or crystalline copolymer of ethylene, e.g., ethylene and methacrylic acid, characterized in that there is present in the blend 1.8 to 8.0 parts by weight of a thermoplastic graft copolymer consisting essentially of a trunk copolymer derived from ethylene and a comonomer providing amine-reactive sites and polycaprolactam side chains linked to said reactive sites through amide or imide linkages. The modified blends are useful as injection molding resins, for wire jacketing, etc.
