HCID 131710947L-lactide epsilon-caprolactone

Procedure

L-lactide-ε-caprolactone copolymer pellets were prepared by carrying out the same procedures as described in Preparation Example 1 except that 216 g of L-lactide was replaced by 108 g of L-lactide and 108 g of ε-caprolactone. The copolymer obtained had an average molecular weight of 70,000.
