In the seeded semicontinuous emulsion copolymerization of methyl methacrylate and n-butyl acrylate, the use of mixed surfactant systems (anionic sodium lauryl sulfate and non-ionic Brij 35 and Glytanox 1001) leads to a decrease in the total particle number in the reactor during the reaction. Moreover, the decrease in the particle number is higher when the emulsifier used is non-ionic. The kinetic behaviour of the process is not influenced by the nature or amount of the emulsifier. The study of the evolution of particle size distribution shows that the distribution becomes broader during the reaction in all the cases studied. The total particle area decreases when the amount of non-ionic emulsifier in the recipe is increased.
