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