Title:
SHAPE-MEMORY RESIN COMPOSITION AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2021/205984
Kind Code:
A1
Abstract:
This shape-memory resin composition contains: a resin (A) having a constitutional unit (a1) represented by general formula (a-1) and a constitutional unit (a2) represented by general formula (a-2); titania nanoparticles (B); and a tetraalkylphosphonium salt (C), and can be thermally melted and molded. In formula (a-1), R1 is a hydrogen atom or the like. Ra1 is a C1-C5 alkyl group. In formula (a-2), R2 is a hydrogen atom or the like. X2 is a nitrogen-containing cyclic group, a group represented by formula (a-2-1), or a group represented by formula (a-2-2). In formula (a-2-2), Ya2 is a C1-C5 alkylene group.
