Abstract

A cross-linked nylon block copolymer comprising a copolymer containing a polyamide block and an elastomeric block, irradiation cross-linked, including a compound which promotes cross-linking therein. In process form, the present invention comprises supplying a nylon block copolymer, containing a polyamide block and an elastomeric block, along with cross-linking promotor and exposing the block copolymer to irradiation, sufficient to cross-link the copolymer and improve mechanical properties therein. The cross-linked nylon block copolymers here have particular utility in both the medical and wire and cable industries.
