Fatemeh Majidi Arlan

Water-soluble cationic co-polymers of acrylamide and diallyldimethyl amoninum chloride was synthesized via free radical polymerization in the presence of Ce (NH4)2(NO3) as an initiator. Synthesized co-polymers were characterized by FTIR, 1H NMR and TG/DSC analyses. Cationic polyacrylamide (CPAM) is a kind of synthetic organic compound with excellent sludge dewatering performance. Cationic polyacrylamides, ammonium-based polymers, poly(allyldimethyl-ammonium chloride), and epichlorohydrin/dimethylamine-based polymers are the most common CPEs used as coagulation and flocculation agents cause they are economical and water-soluble with tunable charge densities at high molecular weights. Free radical polymerization, step-growth polymerization, and post-polymerization modification methods afford each polymer system. CPEs are used for water treatment, anti- microbial materials, and non-viral gene delivery. The cationic degree (CD) is closely related to the electrical neutralization performance of CPAM. Besides, CD can also affect the morphology of CPAM in aqueous solution.
