Lactide Polymerization

Functionalized diaminophenolates as ligands for dinuclear indium catalysts were investigated in the ring-opening polymerization of lactide. An increase in the steric bulk of the ligand phenolates decreases the selectivity of the catalysts due to catalyst dissociation during polymerization.
