POLYLACTIDE RESIN HAVING EXCELLENT HEAT RESISTANCE AND PREPARATION METHOD THEREOF |
摘要 |
The present invention relates to a polylactide resin having excellent heat resistance, a preparation method thereof, and a polylactide resin composition including the same. The polylactide resin is characterized by high polymerization activity owing to an organic coordinated metal catalyst even though it has a low catalyst content, and a molecular weight reduction due to thermal decomposition at high temperature and a rate of thermal decomposition including depolymerization are greatly suppressed by a low catalyst content and a low resin acidity, and thus provided is the polylactide resin having superior heat resistance. |
