Quaternized aminomethyl acrylamide polymer emulsions are treated by 1) adjusting the pH to about 3.6 to about 4.8, 2) adding a formaldehyde scavenger, 3) adjusting the water content of the aqueous phase to result in about 10-45 weight percent of quaternized aminomethylated acrylamide polymer and 4) heating the resultant emulsion at from about 4O°C to about 80°C for about 3 to about 20 hours so as to render them more stable, capable of inversion in water independent of water temperature or pH of the medium flocculant and superior dewatering ability. The quaternized aminomethyl acrylamide polymer emulsions are especially useful as flocculating agent for suspended solids.
季铵化氨甲基丙烯酰胺聚合物乳液的处理方法是:1)将 pH 值调至约 3.6 至约 4.8,2)添加甲醛清除剂,3)调整水相的含水量,使季铵化氨甲基丙烯酰胺聚合物的重量百分比约为 10-45,4)将所得乳液在约 4O°C 至约 80°C 的温度下加热约 3 至约 20 小时,使其更加稳定,能够在水中反转,不受介质絮凝剂的水温或 pH 值的影响,脱水能力更强。季铵化氨基甲基丙烯酰胺聚合物乳液尤其可用作悬浮固体的絮凝剂。
