摘要： The present invention relates to a semi-aromatic polyamide and a method for preparing it with low wastewater discharge. The semi-aromatic polyamide for the present invention is obtained by introducing aromatic dicarboxylic acid, aliphatic diamine containing 4˜14 carbon atoms and the wastewater generated during the previous prepolymerization into an autoclave for prepolymerization reaction and then further polymerizing the prepolymer. In this preparation method, the wastewater generated during polymerization is recycled, thus greatly reducing the wastewater discharge; the raw materials in the wastewater are effectively recycled, thus improving the utilization rate of raw materials; meanwhile, the diamine in the wastewater compensates that lost along with water discharge during prepolymerization, thus ensuring the Mole ratio balance between dicarboxylic acid monomer and diamine monomer.
摘要翻译：本发明涉及一种半芳族聚酰胺及其制备方法，废水排放量低。本发明的半芳族聚酰胺通过将芳香族二羧酸，含有4〜14个碳原子的脂族二胺和前述预聚合中产生的废水引入高压釜中进行预聚合反应，然后进一步聚合预聚物而得到。在这种制备方法中，聚合过程中产生的废水回收利用，大大减少了废水排放; 废水中的原料被有效回收，从而提高了原料的利用率; 同时，废水中的二胺补偿了预聚合过程中随着排水的流失，保证了二元羧酸单体与二胺单体之间的摩尔比平衡。
