Ultrafast ring-opening copolymerization of lactide with glycolide toward random poly(lactic-co-glycolic acid) copolymers by an organophosphazene base and urea binary catalysts

Random PLGA copolymers with tunable monomer sequence lengths were prepared by one-pot ring-opening copolymerization (ROCOP) of LA with GA using an organophosphazene base/urea binary catalyst.
