Abstract

Bio-degradable polyester copolymer having L-lactic acid and/or D-lactic acid as the main component, in which the lactic acid component is copolymerized with at least one component selected from (A) 0.1 to 15 wt. % of a polyethylene glycol (PEG) having average molecular greater than 300; (B) 0.5 to 15 wt. % of aliphatic polyester; and (C) 0.5 to 15 wt. % of aromatic compound having sulfonic acid group and two ester-forming group, to obtain a product having an average molecular weight greater than 50,000.
