研究了5-甲基-1，3-二氧杂环戊烷-2，4-二酮(LacOCA)的有机金属络合物，包括Co(III)与席夫碱配体、锡甲酸酯和Al(III)与席夫碱配体的开环聚合。在温和的条件下，LacOCA与金属有机络合物在甲苯中进行聚合。通过光谱分析和热分析对聚乳酸进行了表征，揭示了LacOCA聚合的有效催化剂的结构。
The ring-opening polymerization of 5-methyl-1,3-dioxolane-2,4-dione (lacticO-carboxylic anhydride, LacOCA) using organometallic complexes, including Co(III) complexes with Schiff base ligands, Tin(II) alphatates and Al(III) complexes with Schiff base ligands, was explored. The polymerization was carried out by treatment of the organometallic complexes with LacOCA in toluene under mild conditions. The corresponding poly(lactic acid) was characterized by spectroscopy and thermal analyses, which revealed insight into the structure of the effective catalyst for the polymerization of LacOCA.
