반응 단계
The procedure of Example II is repeated except that 15 grams of L-(-)-lactide, 35 grams of epsilon caprolactone and 0.0105 grams of pure stannous octoate catalyst are blanketed with dry nitrogen in a glass flask and heated for 45 hours at 140° to 142° C. The copolymer is tough and elastic and has good tensile strength and elongation properties. The copolymer has
