The effects of the type and amount of surfactant on the overall polymerization features and final product properties for the seeded semicontinuous emulsion terpolymerization of styrene, 2-ethylhexyl acrylate and methacrylic acid were investigated. The emulsifier systems studied included: (i) pure anionic emulsifier (sodium lauryl sulfate); (ii) anionic ethoxylated emulsifier (Alipal CO-436); and (iii) non-ionic emulsifiers of different ethylene oxide chain length (Myrj 45 and Myrj 52). The final latex properties considered were: latex viscosity both prior to and after neutralization, mechanical stability, chemical stability and freeze-thaw stability.
