HIGH-ENERGY RADIATION-RESISTANT ELASTOMERIC VULCANIZATES .1. CHLOROSULFONATED POLYETHYLENE

Abstract

In this article, a detailed study on the stabilization of chlorosulfonated polyethylene (CSP) vulcanizates in gamma radiation is reported. The special additives (antirads) for the stabilization are synthesized from polynuclear aromatics and formulated in the laboratory. The effect of these antirad formulations on the physicochemical structure and performance properties of these materials is studied by monitoring the degradation in gamma radiation using resistivity, wide-angle X-ray diffraction, and mechanical properties. Antirad formulations to stabilize CSP against a total dosage of 200 Mrads of gamma radiation have been achieved. (C) 1994
