The preparation of concentrated St-MAA emulsion by one-step method is investigated. The stability of the emulsion is affected by the kinds and concentration of the emulsifiers, volume fraction and polarity of the monomer. The polymerization of concentrated St MAA emulsion was carried out using azo-bis-isobutyronitrile as initiator. Results indicate that the average size and dispersity of the latex particles depend on the concentration of the surfacant and monomer fraction.
