Abstract

The semi-enclosed solution polymerization is used with a redox system to produce a series of cationic coagulant with terpolymer of methyl acrylyl ethyl trimethyl ammonium chloride(DMC),dimethyl diallyl ammonium chloride(DMDAAC) and acryl amide(AM).And the way to control a few double bond crosslink in the drying process of the terpolymer is studied.From the analysis of different drying processes and conditions,the best production conditions of the terpolymer powder are found.The prepared terpolymer flocculant has good flocculent effect in dealing with papermaking wastewater.
