Synthesis and Study of ternary copolymerized cationic polyacrylamide

The ternary cation flocculant P(AM-DMDAAC-DMC) was synthesized by aqueous solution polymerization with raw materials of acrylamide(AM),and dimethyl diallyl ammonium chloride(DMDAAC) and methacryloyloxyethyltrimethyl ammonium chloride(DMC) with the complex redox as initiator.Effects of cationic mononer ratio,mononer mass fraction,the amount of initiator and reaction temperature on the viscosity of the products were investigated. The results indicate that the viscosity of the copolymer can reach 10.26dL/g, and the terpolymer demonstrates excellent water-solubility.The chemical structure was investigated by IR.
