SEMI-AROMATIC POLYAMIDE RESIN, METHOD FOR PREPARING SAME, AND POLYAMIDE MOLDING COMPOSITION CONSISTING OF SAME

Document Type and Number:

WIPO Patent Application WO/2018/133294

Kind Code:

A1

Abstract:

Disclosed are a semi-aromatic polyamide resin, a method for preparing same, and a polyamide molding composition consisting of same. The semi-aromatic polyamide resin consists of the following components: (A) 20-95 wt% of PA66 homopolymer derived from 1,6-hexamethylenediamine and adipic acid; and (B) 5-80 wt% of PA6T homopolymer derived from 1,6-hexamethylenediamine and terephthalic acid, wherein (A)+(B)=100 wt%. According to the prevent invention, by adding a certain quantity of the PA66 homopolymer into the PA6T homopolymer, the melting point of the PA6T homopolymer can be significantly reduced to below a decomposition temperature, so that the processability of the PA6T homopolymer is improved; the melting point of the prepared semi-aromatic polyamide resin is reduced, and normal processing can thus be performed; the polyamide molding composition consisting of the semi-aromatic polyamide resin has good processability and excellent surface properties, and also maintains a relatively low water absorptivity.
