摘要：

先用酯化的方法合成了含有聚乙二醇(PEG)的降冰片烯大分子单体, 再用开环易位聚合方法使大分子单体聚合, 得到了PEG取代的聚降冰片烯接枝共聚物. 并通过凝胶渗透色谱法（GPC）研究合成的接枝共聚物分子量及分子量分布情况. 结果表明：聚合物的数均分子量为1.0万~4.4万；分子量分布为1.11~1.22, 并且聚合物的分子量分布随［M］/［I］的增加而变窄.

Abstract:

This work focused on the synthesis of norbornene macromonomers with poly(ethylene glycol)(PEG) and the preparation of graft copolymer by ringopening metathesis polymerization (ROMP) of these macromonomers. The molecular weight and polydispersity of graft copolymer were studied by gel permeation chromatography (GPC). It was found that the molecular weight of graft copolymer was between 10 000 and 44 000 with polydispersity between 1.11 and 1.22. Moreover, the polydispersity of the polymer became narrowed with the increase of ［M］/［I］.

Key words: poly(ethylene glycol)(PEG), graft copolymer, ringopening metathesis polymerization, molecular weight, molecular weight distribution
