Abstract: Poly (N,N-diallyl-N-methylpropylammonium chloride) (PMPDAAC) was prepared using N,N-
diallyl-N-methylpropylammonium chloride (MPDAAC) as monomer and 22-azobis (2-methylpropionamidine)
dihydrochloride (V50) as initiator in aqueous solution. On the basis of single factor experiments, the
Box-Behnken mathematical relational model between the intrinsic viscosity values of PMPDAAC and their
affecting factors was established, and the preparation conditions of PMPDAAC were optimized. The
optimum preparation conditions were as follows: the three-steps heating process temperature was 56.1 ℃,
61.2 ℃, 80.2 ℃, respectivity,w(MPDAAC)=71.03%, w(V50)=2.50% and w(Na 4 EDTA)=0.0074%. The
average value of intrinsic viscosity of PMPDAAC and the conversion of monomer under optimal conditions
reached 1.17 dL/g and 92.05%, respectively. The structure of the product was characterized by FTIR and
NMR, and its M w and polydispersity index, d(M w/M n), was measured by GPC-MALLS. The results showed
5
that the maximum M w of PMPDAAC was 2.658×10 , and the polydispersity index was 1.358. The research
indicated that steric hindrance and possible solvent effect caused by substituent propyl group were the main
factors affecting the polymerization activity of diallyl quaternary ammonium salt.
