Abstract

Certain metal compounds such as antimony oxide and magnesium oxide are used to enhance the notched Izod impact resistance of molded objects made from selected polyamide copolymer compositions comprised of polyepsiloncaprolactam (nylon-6) or polyhexamethyleneadipamide (nylon-66) and preferably ethylene/ethyl acrylate and ethylene/acrylic acid copolymers.
