一种半芳香族聚酰胺、其制备方法、其组合物及其应用
摘要：
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。一种半芳香族聚酰胺，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和脂环族二元胺，所述脂环族二元胺的物质的量之和占所述二元胺单体的25-35%。本发明所述的半芳香族聚酰胺，其结晶度较低，玻璃化转变温度较高。本发明所述的聚酰胺组合物，其抗翘曲性能比较好；可以广泛的应用于电子电器领域。
摘要（英）：

The invention discloses semi-aromatic polyamide and a preparation method thereof, and a semi-aromatic polyamide composition and application thereof. The semi-aromatic polyamide is prepared from an aromatic dicarboxylic acid monomer and a diamine monomer, wherein the diamine monomer comprises aliphatic diamines and alicyclic diamines; and the sum of moles of the alicyclic diamines accounts for 25-35% of the diamine monomer. The semi-aromatic polyamide disclosed by the invention is low in crystallinity and high in glass transition temperature. The polyamide composition disclosed by the invention has relatively favorable buckling resistance, and can be widely used in the field of electronic and electric appliances.
