Title:
HIGHLY BRANCHED POLYLACTIDE RESIN, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2023/239090
Kind Code:
A1
Abstract:
The present invention is characterized in that, by using a specific branching agent, a phosphorus compound, and an organic acid anhydride in a polylactide resin, high branching of the polylactide resin, which had not been previously achieved, is possible, and accordingly various physical properties, especially melt strength, are improved compared to conventional polylactide resins, and thus, the present invention can be applied in processes which were difficult to apply to the conventional polylactide resins, such as foam.
