摘　　要：研究了三亚甲基桥联双茚基钐二苯胺化物(C_9H_6CH_2CH_2CH_2C_9H_6)SmNPh_2作为单组分催化剂催化ε-己内脂开环聚合反应,考察了催化剂用量、聚合反应时间和聚合反应温度对ε-己内酯聚合反应的影响。结果表明,配合物对己内酯聚合有较高的催化活性;温度升高,聚合反应的转化率增加,但产物粘均分子量降低。通过粘度法对聚合产物的粘均分子量进行了表征。The ring lanthanide complex and temperature of plex as the catalyst opening polymerization of （ C9 H6 CH2 CH2 CH2 C9 H6 ） ε-caprolactone catalyzed by trimethylene bridged indenyl SmNPh2 and the influence of catalyst dosage,reaction time ε-caprolactone polymerizationon were investigated. The results indicated that the comexhibited high activity;the conversion of the polymerization increased and the viscosi-ty-average molecular weight of the polymers decreased with the increase of temperature. The viscosity-av-erage molecular weight of the polymers was measured by viscosity method.
