二氯化苄/CuCl/2,2′-联吡啶引发甲基丙烯酸甲酯的原子转移自由基聚合

Atom transfer radical polymerization of methyl methacrylate initiated with benzyl dichloride/CuCl/2,2′ bipyridine

在ＣｕＣｌ／２，２′联吡啶配位化合物的催化下，以α，α′二氯化苄为引发剂，进行了甲基丙烯酸甲酯的原子转移自由基聚合。实验结果表明：聚合物的数均相对分子质量与单体转化率成正比，且与理论预计值基本吻合，相对分子质量分布也较窄（Ｍｗ／Ｍｎ＝１２０～１３０）。

The atom transfer radical polymerization of methyl methacrylate initiated by benzly dichloride/CuCl/2,2′ bipyridine was investigated. The results show that the number average molecular weight was proportional to monomer conversion and molecular weight distribution was relatively narrow ( w/ n =1 20～1 30).
