Polymerization of Lactide Catalyzed by Diketiminato Iron (Ⅱ) Alkoxide Complex

摘要：

　　Lactide polymerization.were carried out by using diketiminato iron (Ⅱ) alkoxide complexes HC(C(CH3)N-2,6-1Pr2C6H3)2FeO1Pr as catalyst.The iron (Ⅱ) alkoxide complex bearing bulky isopropyl ortho substituents showed moderate activity for the rac-lactide polymerization,and gave the polylactide (PLA) with high molecular weight.In the microstructures of polymers generated with the iron (Ⅱ) catalyst,no stereoslective polymerization of rac-lactide has been detected.Results have shown that the conversion of lactide depend on the iron complex/monomer feed ratio and the reaction temperature.
