Reaction Steps

In this embodiment, LPLG-b-P(GA-co-CL) copolymer is formed by mixing the L-lactide and glycolide monomers with a solvent and catalyst to form a polymerization solution. Once LPLG is formed in the solution, glycolide monomers and caprolactone monomers are added into the solution containing the formed LPLG copolymer to form LPLG-b-P(GA-co-CL) copolymer. In one embodiment, the glycolide monomers and caprolactone monomers are added to the same solution of LPLG-formed copolymer to allow glycolide and caprolactone monomers to react with LPLG in the solution to form LPLG-b-P(GA-co-CL) copolymer. Alternatively, the glycolide monomers and caprolactone monomers are added in a solution of LPLG which includes different solvent(s).
