Title: Synthesis and Structural Characterization of Copolymer of Dimethyl Diallyl Ammonium Chloride and Acrylamide
Abstract: The factors influencing on the characteristic viscosity in 1 mol/L NaCl aqueous solution at 30℃ of DMDAAC/AM copolymer prepared by redox initiated copolymerization in aqueous solution are investigated: purification of monomer DMDAAC; pH value of reaction mixture (1~5); total concentration of monomers (10-50%); molar ratio of DMDAAC to AM (0.2~1.0); and concentration of initiator K2S2O8NaHSO3 (0.006-0.5%). The copolymerization is conducted at 35℃ in 10 hrs. The DMDAAC/AM copolymer structure is identified by characteristic absorption peaks in its IR spectrum. In treating a black liquor from cellulosepaper making, the flocculating and decolorating capacities of a DMDAAC/AM copolymer prepared is better than that of a commercial flocculant PAM and polyacrylic acid.
