Process for producing bioabsorbable polyhydroxycarboxylic acid |
| abstract |
[PROBLEMS] To provide a method for producing a polyhydroxycarboxylic acid ester having less water-soluble free acid components suitable as a bioabsorbable material than hydroxycarboxylic acids such as lactic acid and glycolic acid. provide. SOLUTION: By using sulfonic acid as a catalyst and polycondensing hydroxycarboxylic acid such as lactic acid and glycolic acid, the amount of water-soluble free acid is 0.0001 mol / g in terms of monobasic acid. Below, the weight average molecular weight is 40 A method for producing a polyhydroxycarboxylic acid ester having a molecular weight of 00 to 100,000 is provided. |
