Abstract

Natural or synthetic elastomers or resins chemically cured at low temperatures are exposed to ionizing radiation, e.g. gamma- or beta-rays, electrons, to improve their mechanical properties, e.g. resistance to impact. The process is applicable to compositions comprising natural rubber, synthetic rubbers such as butadiene copolymerized with styrene, methacrylate or acrylonitrile, butyl rubber, polyisobutylene, copolymers of olefines, graft polymers, gutta-percha, balata, high styrene-butadiene resin, methacrylate-butadiene, cyclized rubber, the chemical curing comprising admixing with sulphur and accelerator, and heating in powdered sulphur at 60 DEG C. or in a carbon disulphide atmosphere to 10 DEG to 90 DEG C.; thereafter the material is subjected to a dosage of from 5 X 106 to 1 X 108 rads in the absence of oxygen. The curing of golf ball covers is described.
