Abstract

Carboxylated polystyrene particles were synthesized by batch emulsion copolymerization of styrene (St) and methacrylic acid (MAA) at 70 °C for 7 h. The effects of introducing time and amount of emulsifier SDS on the polymerization and properties of polymer particles were investigated. Results showed that introducing SDS after initiating polymerization for 3 h was beneficial to forming latex particles with monodisperse size and smooth sphere, and the properties of the resultant particles, including size and size distribution, zeta potential as well as carboxyl distribution were hardly influenced by the amount of SDS in this situation. Furthermore, the mechanism of polymerization was briefly discussed
