Reaction Steps
L-Lactide (220 g), 35 g of glycolide and 45 g of ε-caprolactone were subjected to a polymerization reaction in the presence of 0.01 g of stannous octoate in vacuo (10−3 mmHg) at 150° C. for 24 hours. After the reaction, the product was purified by dissolving in chloroform followed by separating in methanol to give 185g of copolymer of lactic acid, glycolic acid and ε-caprolactone.
