A series of poly(styrene‐ co ‐methacryloxyethylhexadecyldimethyl ammonium bromide), P(St‐DMHB), cationic particles were prepared by emulsion polymerization using 2,2′‐azobis(2‐methylpropionamide) dihydrochloride as the initiator with different levels of DMHB as the cationic functional comonomer. ζ potential, particle size, and size distribution of the particles were determined. Large discrepancy was observed between the particle size from dynamic light scattering and that from transmission electron microscopy. Results showed that particle size and ζ potentials were closely dependant on DMHB level used. A flocculation process for the cationic latex was established, and a method to estimate DMHB conversion was proposed. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
