Document Type and Number:
WIPO Patent Application WO/2021/045075
Kind Code:
A1
Abstract:
The present invention provides a resin composition which enables an aliphatic polycarbonate to exhibit the mechanical properties thereof with good reproducibility, and which is formed into a molded body that has a good balance among mechanical properties such as strength, elongation and fracture toughness. A resin composition according to the present invention contains an aliphatic polycarbonate and a polylactic acid; and with respect to the aliphatic polycarbonate, the area ratio of the region where the molecular weight is 20,000 or less to the entire molecular weight region in the molecular weight distribution curve of the aliphatic polycarbonate as obtained by size exclusion chromatography is from 1% to 30%.
