POLYAMIDOAMINE-EPIHALOHYDRIN RESINS, METHOD OF MANUFACTURE, AND USES THEREOF |
摘要 |
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). |
