“…Practical importance of DADMAC homopolymer and copolymer studies involving polymerization mechanism and kinetics, molecular characterization, and solution properties of this system have drawn great interest. Highly hygroscopic nature of PDADMAC causes difficulties in characterization polymerization reaction by chemical methods or isolation and gravimetrically . The electrostatic repulsion between the ion and the charged macroradical depend on the pH value of the medium and the concentrations of ionic species.…”

Diallyldimethylammonium chloride, which is an acidic salt with numerous applications, was polymerized in water at three different monomer concentrations and at three different pHs which the monomer is in charged form. Reactions were investigated by the automatic continuous online monitoring of polymerization technique. Conversion, molecular weight, and reduced viscosity were monitored. The reaction is found to be second‐order with respect to monomer. Rate constants and molecular weights tend to increase with pH and concentration. POLYM. ENG.
