在氮气保护下
利用预辐照接枝技术在高密度聚乙烯(HDPE)膜上接枝苯乙烯三甲基氯化铵(VBTAC)单体
以甲基丙烯酸二甲氨基乙酯(DMAEMA)单体作为接枝辅助单体来提高VBTAC的接枝率
制备出阴离子交换膜
解决了在HDPE上难以直接接枝聚合VBTAC的问题。本文研究了接枝条件及接枝液的组分对接枝的影响
并用X射线显微分析方法研究了VBTAC的接枝进程和接枝分布。
HDPE films irradiated to 200 kGy in N2 were grafted with vinyl benzyltrimethylammonium chloride(VBTAC)to synthesize a strong base anion-exchange membrane.Comonomer grafting technique was used owing to the difficulty of direct graft polymerization of VBTAC onto polyethylene.Dimethylaminoethyl methacrylate(DMAEMA)
a relative weak acid monomer
was selected as a co-monomer to promote graft polymerization of VBTAC.The grafting conditions
as well as the compositions of grafted films were investigated.The distribution of grafted basic group in polymer substrate was measured by an X-ray microanalyzer.
