Title:
METHOD FOR PREPARING POLYAMIDE BY USING MOLECULAR WEIGHT CONTROL AGENT HAVING DOUBLE ACTIVE GROUP, AND POLYAMIDE PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2019/107756
Kind Code:
A1
Abstract:
The present invention provides: a method for preparing a polyamide by using a molecular weight control agent having a double active group, the method using a molecular weight control agent containing a double active group in the anionic ring-opening copolymerization of a polyamide, thereby enabling molecular weight to be controlled through the addition reaction of the molecular weight control agent; and a polyamide prepared thereby.
