Title:
BIODEGRADABLE POLYESTER RESIN, METHOD FOR PREPARING SAME, AND BIODEGRADABLE POLYESTER FILM COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/234644
Kind Code:
A1
Abstract:
An embodiment relates to a biodegradable polyester resin, a method for preparing same, and a biodegradable polyester film comprising same. The biodegradable polyester resin may have a polydispersity index (PDI) and weight loss rate that satisfy a specific range, thereby improving biodegradability, mechanical properties, such as tensile strength and impact strength, and heat resistance. In addition, when a film is manufactured using the biodegradable polyester resin, defects, such as fume, bubbles, and fisheye, do not occur, such that processability and productivity may be improved.
