以含非对称N2O2配体异丙氧基铝配合物1催化外消旋丙交酯（rac-LA）开环聚合，研究了单体与催化剂的摩尔比、反应时间和反应温度对聚合反应的影响．结果表明，该配合物对丙交酯开环聚合有较好的催化活性，可制得分子量分布为中等程度的聚丙交酯（Mw/Mn=1.26-1.45）．
以含非對稱N2O2配體異丙氧基鋁配閤物1催化外消鏇丙交酯（rac-LA）開環聚閤，研究瞭單體與催化劑的摩爾比、反應時間和反應溫度對聚閤反應的影響．結果錶明，該配閤物對丙交酯開環聚閤有較好的催化活性，可製得分子量分佈為中等程度的聚丙交酯（Mw/Mn=1.26-1.45）．

Analuminumisopropoxide complex1containing an unsymmetric N2O2 ligand was used for ring-opening polymerization of rac-lactide.The influences of the molar ratio of monomer to catalyst,polymerization temperature and time on polymer were studied.The results showed that,the complex is active,and polylactidewith moderate polydispersity was produced(Mw/Mn=1.26-1.45).
