Abstract: 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.
Abstract translation: 本发明涉及耐热性优异的聚丙交酯树脂及其制备方法以及包含其的聚交酯树脂组合物。 聚丙交酯树脂的特征在于由于有机配位金属催化剂而具有高聚合活性，即使其催化剂含量低，并且由于高温下的热分解和包括解聚在内的热分解速率引起的分子量降低被 低催化剂含量和低树脂酸度，因此提供了具有优异耐热性的聚丙交酯树脂。
