Abstract
The poly(3‐methacryloylamido propyl trimethyl ammonium chloride) (PMAPTAC) was synthesized by radical polymerization in aqueous solution polymerization using ammonium persulfate (APS) and 2,2′‐azobis(2‐methylpropionamide) dihydrochloride (V50) as initiator, respectively. The kinetics of polymerization were examined by changing various monomer and initiator concentrations via the dilatometer method at a low conversion level. The results showed that the polymerization rate grew with increasing monomer, initiator concentrations, and temperatures. The activation energies of polymerization were EaA = 153.09 kJ/mol and Eav = 144.76 kJ/mol. The overall polymerization rate equation for the PMAPTAC were Rp = k[MA]1.64[IA]0.71 and Rp = k[MV]1.57[IV]0.91 at the temperature of 45°C for APS and V50, respectively. Based on the experimental results, the effect on the polymerization rate of different initiators was discussed. The studies supplied the experimental basis of the kinetics for the reaction control of PMAPTAC production.
