Title:
POLYLACTIC ACID RESIN VAPORIZATION PROMOTER AND COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2023/167547
Kind Code:
A1
Abstract:
An embodiment of the present invention pertains to: a composition which contains at least 10 wt% and less than 100 wt% of a polylactic acid (PLA) resin on the basis of the total weight of the composition and has a degree of vaporization (V10w) of 50% or more as obtained by measuring the cumulative amount of carbon dioxide (CO2) generated after 10 weeks at 30°C; and a polylactic acid (PLA) resin vaporization promoter for promoting the vaporization of the polylactic acid (PLA) resin. The polylactic acid (PLA) resin vaporization promoter can significantly accelerate the vaporization of a polylactic acid (PLA) resin having a low degree of vaporization at a room temperature of 30°C, and thereby improve the biodegradation of the polylactic acid (PLA). Thus, the composition containing the polylactic acid (PLA) resin vaporization promoter can be used in various fields and exhibit excellent physical properties while effectively preserving the environment.
