Schiff Base Transition Metal Complexes for ROP of L-Lactide

S. Mantri, H. C. Pradhan, T. Maharana, and A. K. Sutar
Abstract—A Series of Schiff base transition metal complexes have been synthesized and its reactivity for the ring-opening polymerization (ROP) of lactide has been studied. These metal complexes were synthesized by the reactions of metal salt solution with one molar equivalent of bulky Schiff-base ligand in methanol under nitrogen atmosphere. These complexes have been tested as initiators for the ring-opening polymerization of lactide with variation of concentration, time, solvent, etc. The transition metal complexes allow controlled ring-opening polymerization as shown by the linear relationship between the percentage conversion and the number-average molecular weight.

Index Terms—Lactide, polymerization, ROP, schiff base, transition metal.
