| titleOfInvention | Method for producing aqueous solution of poly-α-hydroxyacrylate |
| abstract | (57) Abstract: A polylactone compound corresponding to poly-α-hydroxyacrylic acid is reacted with an aqueous alkali solution in the presence or absence of a peroxide such as hydrogen peroxide to obtain poly-α. In the step of obtaining the aqueous solution of hydroxyacrylate, the alkali is added in portions. [Effect] A PHA salt aqueous solution having a high concentration of 25% by weight or more and less coloring can be obtained without passing through a concentration step, and the generation of by-products is extremely small, and the operation is stable without burdening the stirrer. I can do it. |
