Glycolic acid (GA) was copolymerized with various lactones such as 7-butyrolactone (BL), 6-valerolactone (VL) and E-caprolactone (CL) in the presence of water without catalysts at 200Β°C under N2, giving relatively low molecular weight polyesters. This reaction is characterized by direct condensation
