【摘要】 研究了添加少量三甲基丙烯酸三羟甲基丙烷酯条件下二元乙丙共聚物的辐射交联。结果表明，交联密度正比于剂量和单体含量，而溶胶分数与剂量间的关系偏离Ｃｈａｒｌｅｓｂｙ－Ｐｉｎｎｅｒ关系式。通过引进假设，基于统计理论结果提出了一个半经验式。用该式能较好地解释实验结果，并能与文献数据相符。更多还原

【Abstract】 The radiation crosslinking of ethylene-propylene copolymer containing trimethylolpropane trimethacrylate was investigated.Results showed that crosslinking density varied proportionally with dose and monomer contents, and the relationship between sol fraction and dose deviated from Charlesby-Pinner Equation. Based on statistical theory results, an assumption was suggested in and a semi-experimental formula was obtained which agreed well with experiments.更多还原
