摘要

用,60,Co γ射线辐照聚烯烃弹性体（Polyolefin elastomer，POE）。研究了吸收剂量、辐射敏化剂对POE交联密度的影响，辐照对POE力学性能（拉伸强度和断裂伸长率）以及阻燃性能的影响。POE在空气和氮气中的辐射交联,G,值分别为0.13和0.14。POE的交联密度随吸收剂量和辐射敏化剂的增加而增加；POE经辐射后拉伸强度和氧指数有所提高，断裂伸长率随辐射剂量的增加略有下降。

Abstract

Polyolefin elastomer was irradiated in air or N,2, to different doses by ,60,Co γ-rays. Gel fraction, mechanic performance and flame retarding property of the irradiated POE were investigated. G value of the POE crosslinked in air or N,2, is 0.13 and 0.14, respectively. Gel fraction of the irradiated POE increased with both absorbed dose and sensitizer content, and the value of tensile strength and oxygen index (OI) increased to some extent after irradiation. The value of break at elongation decreased slightly after irradiation.
