Title:
ALIPHATIC POLYESTER COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2020/230807
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a stretchable polyester that has flexibility and shape followability through elastic response and that is capable of suppressing degradation over time caused by secondary crystallization. The present invention provides a stretchable polyester that is an aliphatic copolymerization polyester including two or more types of monomer units and that includes an α structure and an amorphous structure, wherein the X-ray orientation degree of the α structure is 50% or more.
