SYNTHESIS OF β-DIKETIMINATE DERIVATIVES OF ZINC ALKOXIDES: CATALYTIC PROPERTIES FOR RING OPENING POLYMERIZATION

A series of zinc (II) complexes has been prepared based on a β-diketiminate ligand framework and exhibits the highest rate of polymerization with better stereoselectivity in the formation of polylactic from the rac-lactide with aggregation and narrow polydisperties. Degree of aggregation an...
