Document Type and Number:
WIPO Patent Application WO/2022/209378
Kind Code:
A1
Abstract:
Provided is a glycolic acid copolymer composition which can be solidification/extrusion-molded and can be molded into a molded article having an improved thickness decreasing rate during decomposition. The glycolic acid copolymer composition according to the present invention comprises: a glycolic acid copolymer in which at least two linear polymer chains A each composed of a repeating unit derived from glycolic acid are chemically bound to a specific polymer chain B that is different from the polymer chain A; and a carboxylic acid anhydride. The weight average molecular weight of the composition is 150000 or more.
