摘要
用共辐照电子束辐射接枝方法,研究了轻质氧化镁接枝甲基丙烯酸甲酯(MMA)体系的辐照后效应和金属离子效应。通过对接校率、平均分子量的研究结果表明,后效应是接枝链上长寿命的自由基或离子在脱离辐照场后继续聚合的结果。CU2+在非水体系户对均聚物具有较好的阻聚效果。
The effects of the post-radiation and the metal ion have beenstudied on the grafting reaction of methyl methacrylate onto light MgO with themutual radiation method of election beam. The resultS showed that the POst-radiationeffect is that long-lived radical or ion in the grafting link continued polymerizationoff radiation field and Cu2+ in non water system might indibite homopolymer. t
