Title:
BIONYLON HAVING TRIPLE SHAPE MEMORY PROPERTIES, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/039127
Kind Code:
A1
Abstract:
Provided is a method for preparing nylon having triple shape memory properties, comprising the steps of: generating amino acid, containing a biomass-derived pyrrolidone group, by using itaconic acid and a diamine; and generating a nylon copolymer by reacting the amino acid containing the pyrrolidone group and an α,ω-aliphatic amino acid. Therefore, provided is a bionylon having triple shape memory properties, capable of shape deformation, fixing and recovery through two steps, and adjusting shape recovery temperature to a desired level by controlling the amount of a reactant.
