| titleOfInvention | Method for producing polyhydroxycarboxylic acid |
| abstract | (57) [Summary] [Structure] A hydroxycarboxylic acid or an oligomer thereof is blown into an organic solvent with an inert gas and then heated while allowing the inert gas to flow out of the reaction system. A method for producing a polyhydroxycarboxylic acid having a weight average molecular weight of 15,000 or more by a dehydration condensation reaction. [Effect] A high molecular weight polyhydroxycarboxylic acid can be obtained by direct dehydration polycondensation from hydroxycarboxylic acids containing at least lactic acid. |
