Semi-aromatic polyamide, its preparation method, its composition and its application

一种半芳香族聚酰胺、其制备方法、其组合物及其应用

Abstract

The invention discloses a semi-aromatic polyamide, its preparation method, its composition and its application. The semi-aromatic polyamide is prepared from an aromatic dicarboxylic monomer and a diamine monomer, wherein the diamine monomer comprises an aliphatic diamine and also comprises an ortho aromatic diamine and/or a meta aromatic diamine. The semi-aromatic polyamide and its composition disclosed in the invention have high melting points, so the semi-aromatic polyamide and its composition have the advantages of use at a high temperature, low crystallization degree, high glass-transition temperature and good fluidity, and can be widely applied to the electronic and electrical fields.
本发明公开了一种半芳香族聚酰胺、其制备方法、其组合物及其应用。由芳香族二羧酸单体和二元胺单体制备而成,所述二元胺单体包括脂肪族二元胺,所述二元胺单体还包括下述物质中的至少一种:邻位芳香族二元胺和/或间位芳香族二元胺。本发明所述的半芳香族聚酰胺及其组合物,由于其熔点较高,可以在高温下使用,且结晶度较低,玻璃化转变温度较高,且流动性较好,可以广泛的应用于电子电气领域。
