Efficient synthetic approach to copolymers of glycolic and lactic acids for biomedical applications

An efficient approach to copolymers of glycolic and lactic acids applied in biomedical materials was developed using ring-opening polymerization catalysts based on alkoxy complexes of 'biometals' (Mg, Al, and Zn) and 3-methyl- 1,4-dioxane-2,5-dione and glycolide as comonomers.
