摘要
基于近年来铋类催化剂应用于环酯开环聚合的研究成果,尝试将其用作催化乙交酯开环聚合的催化剂。铋类催化剂与传统的锡类催化剂相比,具有低毒性的特点,其催化制备的产物分子量较高且分子量分布较窄。铋类催化剂极可能是催化合成聚乙醇酸的高效低毒催化剂。
In summary,the research results of use of bismuth catalyst for the ring-opening polymerizationof cyclic ester have been summarized.They have been used as catalysts for catalyzing the ring-opening polymer-ization of glycolide.Bismuth catalyst has low toxicity compared with traditional tin catalyst,and its catalyticallyprepared product has relatively high molecular weight and narrow molecular weight distribution.Bismuth cata-lyst is likely to be highly efficient and low-toxic catalyst for the synthesis of polyglycolic acid.
