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

Abstract:

Lactide polymerization were carried out by using diketiminato iron (II) alkoxide complexes HC(C(CH3)N-2,6-iPr2C6H3)2FeOiPr 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.
