Title:
BIODEGRADABLE AQUEOUS DISPERSION SOLUTION, AND BIODEGRADABLE PRODUCT AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/234670
Kind Code:
A1
Abstract:
The present invention relates to a biodegradable aqueous dispersion solution, and a biodegradable product and a manufacturing method therefor. Specifically, according to one embodiment of the present invention, a biodegradable aqueous dispersion solution comprises a polyhydroxyalkanoate, water and a polyol, which has an average degree of polymerization of 100-25,000, so as to have a drying rate at 170°C, according to relation 1, of 7.0 g/m2·s or less, and thus has excellent biodegradability and biocompatibility, thereby improving pH, viscosity characteristics, dispersibility and storage stability while being eco-friendly.
