Two novel well-defined star-graft copolymers with poly as main chain are successfully prepared by combination of anionic and atom transfer radical polymerization. Anionic copolymerized 2,5-epoxypropyl-1-ethoxyethyl ether with EO by initiation of mixture of diphenylmethylpotassium and polyol [1,1,1-trispropane or pentaerythritol] to give the well-defined three-arm star poly and four-arm star poly.

用核磁共振(~1H NMR)、红外光谱、元素分析、气相色谱—质谱、凝胶渗透色谱和基质辅助激光解吸附电离飞行时间质谱(MALDI-TOF-MS)等手段对中间产物及最终产物进行了详细地表征，证明了这种合成聚醚为主链的接枝共聚物的方法是可行的，并且是成功的。2。
