Alkaline earth (Ae) metal complexes of the amidophosphine borane ligand are highly active and iso-selective catalysts for the ring opening polymerization (ROP) of rac -lactide (LA). The polymerization reactions are well controlled and produce polylactides with molecular weights that are precise and narrowly distributed. Kinetic studies reveal that the ROP of rac -LA catalyzed by all Ae metal complexes had first-order dependency on LA concentration as well as catalyst concentration. A plausible reaction mechanism for Ae metal complex-mediated ROP of rac -LA is discussed, based on controlled kinetic experiments and molecular chain mobility.
