A NaPSS‐ b ‐PS was prepared via a two‐stage stable free‐radical polymerization using a mixture of ethylene glycol and water as the medium. Styrene emulsion polymerization was conducted using a mixture of NaPSS‐ b ‐PS and SDS. Results showed that there is little aggregation among particles. Two other NaPSSs with different sulfonation fractions were also compared. Comparisons were made using relationships, such as $ {\overline n} $ versus D v , chain growing time versus SDS content, and D v versus SDS content. Characteristic behaviors of various NaPSSs on entry were revealed. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
