| titleOfInvention | Method for recovering lactide from polylactic acid or its derivatives |
| abstract | In order to chemically recycle polylactic acid or a derivative thereof or a resin composition containing the same, a method of depolymerizing polylactic acid or a derivative thereof to efficiently recover and produce lactide having a high optical purity is provided. Thus, a mixture of polylactic acid or a derivative thereof and aluminum hydroxide is thermally decomposed in a temperature range not lower than the melting temperature of polylactic acid or a derivative thereof and not higher than 320 ° C. to recover lactide. |
