| Abstract: | Kinetics of chemical oxidative dispersion polymerization of 3,5‐xylidine (Xy) in aqueous medium with ammonium persulfate (APS) as an oxidant was studied by monitoring the amount of proton released from Xy monomer, which was obtained from the amount of potassium hydroxide (KOH) solution added to keep constant pH values using a pH stat. The initial polymerization rate (R) mol/L/min] of Xy was expressed as follows: R = 1.65 (1 − α) Xy] APS], where α is the degree of ionization of Xy, and Xy] and APS] are concentrations of Xy and APS, respectively. © 2000 John Wiley & Sons, Inc.
