epsilon-CAPROLACTONE → Lactic acid hydroxycaproic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | epsilon-CAPROLACTONE | HCID 10401 | — |
| Reactant | Lactide, L- | HCID 107983 | — |
| Product | Lactic acid hydroxycaproic acid | HCID 86747420 | — |
Reaction Steps
The same procedure as in Preparation Example 4 was effected except that 6 mols of L-lactide and 14 mols of ε-caprolactone were used, thereby obtaining a lactic acid-hydroxycaproic acid copolymer (hereinafter referred to as "PCLA2"). This PCLA2 had a weight average molecular weight of 72000, and a molar ratio of a lactic acid unit to a hydroxycaproic acid unit in the copolymer was 33 to 67.
