Highly branched polylactide resin and preparation method thereof

The present disclosure has the characteristics of achieving a high degree of branching of a polylactide resin, which has not been achieved so far, by using a specific branching agent and a phosphorus-based compound and an acid anhydride-based compound in the polylactide resin, and can also be applied to processes which are difficult to apply to conventional polylactide resins such as expansive foams. 本公开具有以下特征：通过在聚丙交酯树脂中使用特定的支化剂和磷系化合物和酸酐类化合物，可以实现迄今尚未实现的聚丙交酯树脂的高支化度，并且其还可以应用于难以应用于常规聚丙交酯树脂诸如膨胀泡沫的工艺。
