ABSTRACT:
An improved process for cross-linking a shaped polyethylene is herein disclosed comprising irradiating it with electron beams using 0.2 to 2 parts by weight of amine alone or in combination with 0.2 to 1.0 part by weight of alcohol for 100 parts by weight of polyethylene to thereby improve the electrical, mechanical, thermal and other characteristics of the polyethylene.
