Outline of Final Research Achievements

A new organo catalytic system inspired by enzyme was developed to give a variety of “precise poly (lactic acid) s” with exactly molar mass and designed chemical structures quantitatively. The organo catalyst is highly active for ring opening polymerization and efficient to design polymer structures as introduction of multi-branching, initial- and terminal- functionalization and block copolymerization. Then many designed linear- and branched- poly (lactic acid) s with narrow polydispersity were obtained easily by selection of corresponding initiators, terminators, monomer/initiator ratio and monomer types. Some industrial candidates for new plastics materials have been found from them by controlling their flexibility and heat resistance.
