- W2367804705 abstract "Taking dimethyldiallylammonium chloride(DMDAAC) and acrylamide(AM) as raw materials,and ammonium persulfate-sodium bisulfate redox complex as the initiator,the copolymers of poly DMDAAC and AM(PDA) with 10% and 20% cationicity are prepared.The effects of the monomer mass,initiator dosage,reaction temperature and the Na4EDTA dosage on the intrinsic viscosity of PDA are studied.The results show that,under the optimum technological condition that the monomer mass percentage is 20% and 37.5%,the mass ratio of initiator to monomer is 3.0×10-4 and 5.1×10-5,the reaction temperature is 45℃,and the mass ratio of Na4EDTA to monomer is 2.0×10-4,the intrinsic viscosities of PDA with 10% and 20% cationicity are 17.1 dL/g and 12.2 dL/g respectively.The different optimum parameters are caused by the differences between the reactivity ratios of two monomers." @default.
