丙烯酰胺-甲基丙烯酰氧乙基三甲基氯化铵共聚物的制备研究

Manufacture and research of acrylamide-methyl acryloyl oxygen ethyl trimethyl ammonium chloride copolymer

用过硫酸铵(KPS)引发甲基丙烯酰氧乙基三甲基氯化铵(DMC)与丙烯酰胺(AM)单水相共聚,制备了阳离子聚丙烯酰胺类絮凝剂P(DMC-AM),并应用于废水。探讨了单体总量、引发剂用量、pH值、反应时间等因素对聚合物的特性粘数和粘均分子量的影响。结果表明,P(DMC-AM)粘均分子量可达1.72×107g/mol,对废水浊度的去除率达到80%以上,是一种性能优良的絮凝剂。

Using ammonium persulfate（ KPS ）trigger with methacryloyl ethyl trimethyl ammonium chlo-ride（ DMC）and acrylamide（ AM）in a single aqueous phase to prepare a cationic polyacrylamide lactic flocculent（CPAM）and used in the wastewater. Discussing about total monomer,initiator dosage,pH,reaction time and other factors affect the intrinsic viscosity and viscosity-average molecular weight of polymer. The results show that P（ DMC-AM）viscosity-average molecular weight can be up to 1. 72 ×10^7 g/mol, the effluent turbidity removal rate reached more than 80%,the product is a kind of flocculant of excel-lent performance.
