摘要

研究了电子束辐照交联法制备的三甲基丙烷三甲基丙烯酸酯(TMPT)高分子单体对天然橡胶和三元乙丙橡胶(EPDM)物理性能的影响。本文还报道了聚能单体TAC(三烯丙基氰脲酸酯)的浓度对EVA(醋酸乙烯酯)橡胶和CPE(氯化聚乙烯)橡胶物理性能的影响。讨论了加速EB和2.45 GHz微波(MW)同时辐照对含TAC硅橡胶物理性能影响的几个结果。在适当的多官能团单体浓度和适当的EB剂量下，橡胶的物理性能与用过氧化苯甲酰经典方法制备的对照样品相比得到了改善。通过EB+MW处理获得的最重要的结果是，在相同的硫化参数下，与单独的EB辐照相比，EB的剂量减少了。

Radiation processing of rubber mixtures with polyfunctional monomers

The concentration effect of the polyfunctional monomers TMPT (trimethylopropane trimethacrylate) on the physical properties of the natural rubber and of the EPDM (Ethylene-propylene-terpolymer) rubber, crosslinked by electron beam (EB) irradiation, is presented. Also, the concentration effect, of the polyfunctional monomer TAC (triallylcyanurate) on the physical properties of EVA (ethylene vinyl acetate) rubber and of the CPE (polyethylene chlorinated) rubber, obtained by EB vulcanization, is reported. Several results regarding the effect of simultaneous irradiation with accelerated EB and 2.45 GHz microwaves (MW) on the physical properties of the silliconic rubber containing TAC are discussed. For the proper polyfunctional monomers concentrations and proper EB doses the rubber physical properties are improved with respect to control samples obtained by classical procedure using benzoyl peroxide. The most important result obtained by the EB+MW treatment is the reduction of the EB dose compared to the separate EB irradiation, at the same vulcanization parameters.
