METHOD OF SHAPE-MEMORIZING BIODEGRADABLE SHAPE-MEMORY POLYMER MOLDING PRODUCT AND ITS SHAPE RESTORATION

摘要

PROBLEM TO BE SOLVED: To provide a polymer composition that shows biodegradability and melt-moldable shape-memory properties and its molding method. SOLUTION: This polymer composition comprises a polymer blend composition mainly containing the polylactide and poly (ε-caprolactone) in which the content of the polylactide ranges from 25 wt.% to 95 wt.%. In the molding process of the biodegradable shape-memory polymer composition, the biodegradable shape-memory polymer composition is characteristically molded into prescribed shaped as fibers, films, sheets and the like.
