    • A novel process for producing a polyamidoamine-epihalohydrin resin composition comprises (a) reacting a polyamidoamine with epihalohydrin to obtain a reaction mixture comprising a polyamidoamine-epihalohydrin resin; (b) adding a first acid to the reaction mixture obtained in step (a) to obtain an acid treatment composition; (c) adding a base to the acid treatment composition in step (b) to obtain a base treatment composition; and (d) adding a second acid to the base treatment composition in step (c) to obtain a polyamidoamine-epihalohydrin resin composition; wherein the polyamidoamine-epihalohydrin resin composition obtained in step (d) has less than about 700 ppm of dihalopropanol (DHP) and 3-halopropanediol (HPD).
    • 制备聚酰胺胺 - 表卤代醇树脂组合物的新方法包括(a)使聚酰胺胺与表卤代醇反应,得到包含聚酰胺胺 - 表卤醇树脂的反应混合物; (b)向步骤(a)获得的反应混合物中加入第一种酸,得到酸处理组合物; (c)在步骤(b)中向酸处理组合物中加入碱以得到碱处理组合物; 和(d)在步骤(c)中向基础处理组合物中加入第二种酸以获得聚酰胺胺 - 表卤代醇树脂组合物; 其中在步骤(d)中获得的聚酰胺胺 - 表卤代醇树脂组合物具有小于约700ppm的二卤丙醇(DHP)和3-卤代丙二醇(HPD)。
