中文摘要	ring-opening polymerization of epsilon-caprolactone (cl) catalyzed by lanthanocenes, o(c2h4c5h3ch3)(2)ycl (cat-ycl) and me2si[(ch3)(3)sic5r3](2)ndcl (cat-ndcl) has been carried out for the first time. it has been found that both yttrocene and neodymocene are very efficient to catalyze the polymerization of cl, giving high molecular weight poly(epsilon-caprolactone) (pcl). the effects of [cat]/[epsilon-cl] molar ratio, polymerization temperature and time, as well as solvents were investigated and polymerization temperature is found to be the most important factor affecting the polymerization. the bulk polymerization gives higher molecular weight pcl and higher conversion than that in solution polymerization. nabph4 was found to promote the polymerization of epsilon-caprolactone, and thus to increase both the polymerization conversion and mw of poly(epsilon-caprolactone).
