Fatty Amine Initiator Lead To A Preliminary Study Of The Synthesis Of 20% Cationic Pda

PreAratiion technology of polymer poly(dimethyldiallylammonium chloride-acrylamide) with cationicity 20% was studied in this peper. Using simply refined cationic monomer P₅ solution as raw material monomer, adopting three kinds of redox complex such as ammonium persulfate with primary-aliphaticamine, seconBry-aliphaticamine, andtertiary-aliphaticamine as an initiator respectively , polymerization technologies of PDA with cationicity 20% was investigated. Especially, through a series of preliminary experiments , orthonormal experiments and effect experiments of technological Arameters, the three optimal technologies were reached respectively。 The intrinsic viscosity of PDA with cationivity 20% reached 12. 9dL · g^-1, 12. 4dL·g^-1 and 12. 2dL · g^-1, respectively , corresponding to above three optimal technologies.
