\nCationic organic polymer flocculant P (am-dmdaac-odma) was prepared by aqueous solution copolymerization with am as the main body, cationic monomer DMDAAC and hydrophobic monomer ODMA, ammonium persulfate as initiator. The effects of total mass fraction of monomer, monomer ratio, initiator concentration and reaction temperature on the intrinsic viscosity and cationic degree of polymerization products were investigated. The prepared P (am-dmdaac-odma) was analyzed by infrared spectroscopy to verify the irregular polymerization effect between monomer am, DMDAAC and ODMA.
