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

In this article, a detailed study on the stabilization of chlorosulfon ated polyethylene (CSP) vulcanizates in gamma radiation is reported. T he special additives (antirads) for the stabilization are synthesized from polynuclear aromatics and formulated in the laboratory. The effec t of these antirad formulations on the physicochemical structure and p erformance properties of these materials is studied by monitoring the degradation in gamma radiation using resistivity, wide-angle X-ray dif fraction, and mechanical properties. Antirad formulations to stabilize CSP against a total dosage of 200 Mrads of gamma radiation have been achieved. (C) 1994 John Wiley & Sons, Inc.
