Title:
PROCESS FOR POLYMERIZING POLYESTERAMIDE
Document Type and Number:
WIPO Patent Application WO/2021/218648
Kind Code:
A1
Abstract:
The present invention provides a process for polymerizing a polyesteramide, characterized by the polymerization raw material comprising in parts by mass: 5-60 parts of polymerization monomers, i.e. a dibasic acid and/or dibasic acid ester; 3-50 parts of a diamine; and 10-90 parts of a reactive dispersion medium, i.e. a polyester and/or polyester amide. The process comprises evenly dispersing the polymerization monomers into the molten reactive dispersion medium, and subjecting same to a polymerization reaction so as to obtain a polyesteramide with a suitable molecular weight. The present invention can significantly improve the production efficiency of the polyesteramide.
