中文摘要：

观察到溴化丁基胶（BIIR）在加速器产生的电子束辐照下可发生交联反应,测得其凝胶化剂量为12 kGy.在剂量较低时辐照产物的凝胶含量与交联密度均随剂量增加而提高,但在80 kGy后则随剂量增加而呈下降趋势.试验了5种多乙烯基单体以敏化BIIR的交联反应,从而避免高剂量下的降解现象.结果表明TMPT（三甲基丙烯酸三羟甲基丙烷酯）是有效的敏化剂,配有TMPT的BIIR交联产物其拉伸强度随TMPT用量增大而明显提高.

英文摘要：

Radiation crosslinked product of bromobutyl rubber （BIIR） was achieved by electron beam （EB） irradiation curing. Gelling dose of BIIR was estimated to be 12 kGy. Various polyvinyl monomers were tested to enhance EB crosslinking of BIIR in order to obtain a high crosslinking degree at a low dose to avoid main chain degradation under high dose irradiation. It was found that TMPT （trimethylolpropane trimethacrylate） was the most effective crosslinking sensitizer to increase the crosslinking density of BIIR. The tensile strength of EB crosslinked BIIR was significantly improved by using TMPT as the sensitizer.
