Document Type and Number:
WIPO Patent Application WO/2024/063024
Kind Code:
A1
Abstract:
Provided is a biodegradable polyurethane resin that is unlikely to generate strongly toxic aromatic amines and that exhibits excellent mechanical properties (strength, toughness) that permit actual use as a molded body. The biodegradable polyurethane resin of the present disclosure has a structural unit derived from a polylactone polyol and a structural unit derived from a C7 or higher aliphatic diisocyanate having no side chains. Also, the method for producing the biodegradable polyurethane resin of the present disclosure has a step that reacts components containing at least a polylactone polyol and a C7 or higher aliphatic diisocyanate having no side chains.
