Title:
METHOD FOR PRODUCING POLYAMIDE USING TERMINAL ENCAPSULANT AND POLYAMIDE PRODUCED THEREBY
Document Type and Number:
WIPO Patent Application WO/2019/107755
Kind Code:
A1
Abstract:
The present invention provides a method for producing a polyamide using a terminal encapsulant, and a polyamide produced thereby, wherein the method is an eco-friendly process method without using a solvent as a catalyst and can prepare, by using a terminal encapsulant for suppressing side reaction, a polymer having a uniform molecular weight and a high conversion rate at a low temperature within a short polymerization time in comparison with a conventional polymerization method.
