| titleOfInvention | Process for producing polylactic acid or copolymer thereof |
| abstract | [PROBLEMS] To efficiently produce polylactic acid or a copolymer thereof having a high molecular weight, a high melting point, and excellent thermal stability and hue. Lactic acid having a total content of metal impurities of 60 ppm or less with respect to the main material and an iron content of 1 ppm or less with respect to the main material, preferably an acetic acid content of 300 ppm or a methanol content of 50 ppm or less. And / or a derivative thereof as a main raw material and a direct polycondensation reaction without solvent. A process for producing polylactic acid or a copolymer thereof. [Selection figure] None |
