Title:
POLYAMIDE RESIN, POLYAMIDE RESIN COMPOSITION, MOLDED BODY AND METHOD FOR PRODUCING POLYAMIDE RESIN
Document Type and Number:
WIPO Patent Application WO/2024/071402
Kind Code:
A1
Abstract:
The present invention provides a polyamide resin which is a copolymer of a biodegradable polyamide such as polyamide 2 to polyamide 4, and another polyamide, and which has further enhanced biodegradability. This polyamide resin comprises a structural unit represented by formula (1) and another polyamide structural unit; and the difference between the degree of randomness in the case where it is assumed that the structural units are in an ideal random arrangement as determined by the proportions of the structural units obtained by 1H-NMR analysis and the degree of randomness obtained from the ratio of carbonyl carbon atoms of amide groups that connect different structural unit to each other to the integral value of all peaks of the carbonyl carbon atoms as obtained by 13C-NMR analysis is 0.10 or less. (In formula (1), x is an integer of 1 to 3.)
