Synthesis, Characterization, and Flocculation Properties
Abstract. A water soluble branched cationic polyacrylamide (BCPAM) was synthesized using solution polymerization. The polymerization was initiated using potassium diperiodatocuprate, K 5 [Cu(HIO 6) 2](Cu(III)), initiating the self-condensing vinyl copolymerization of acrylamide and acryloxyethyltrimethyl ammonium chloride (DAC) monomer.The resulting copolymer was characterized by the use of
