Procedure

The same procedure as in Preparation Example 3 was effected except that 1441 g (10 mols) of L-lactide, 1140 g (10 mols) of ε-caprolactone and 10 ml of a toluene solution containing 0.26 g of stannous octoate, and 5 g of lauryl alcohol were used and that reaction was carried out at 160° C. for 10 hours, thereby obtaining a lactic acid-hydroxycaproic acid copolymer (hereinafter referred to as "PCLA1").
