二甲基二烯丙基氯化铵－丙烯酰胺的合成及其在含油污水处理中的应用

以二甲胺、氯丙烯等为原料合成二甲基二烯丙基氯化铵（ＤＭＤＡＡＣ），再与丙烯酰胺（ＡＭ）共聚生成共聚物。利用胶体滴定法测定共聚物的阳离子度、一点法测定特性粘数，并利用充气浮选法对阳离子共聚物进行浮选效果评价。结果表明，当产品的阳离子度在３０％～４０％的范围内除油效果最好，其效果明显优于阳离子聚丙烯酰胺（ＣＰＡＭ），与复配的聚合铝加聚丙烯酰胺（ＰＡＣ＋ＰＡＭ）相当。

Synthesis of copolymer of dimethyldiallylammonium chloride with acrylamide and its application for treating oil sewage

Dimethyldiallylammonium chloride(DMDAAC) and copolymer comprising DMDAAC and acrylamide(AM) have been synthesized from dimethylamine ,allylchloride and AM. The cation degree of the copolymers is determined by a colloid titration method its intrinsic viscosity is measured by one-point method, and its deoiling effects were evaluated by means of aerated floatation process. The result shows that when cation degree is in the range of 35%～40%, the copolymer has optimal deoiling effect, which is better than that of the CPAM andis comparable to that of the composite comprising(PAC+PAM).
