Miniemulsion copolymerization of styrene/butyl acrylate was investigated by redox initiator(NH_4)_2S_2O_8/NaHSO_3 at lower temperature and contrasted it to convention emulsion polymerization. Monomer droplet of the former is several ten times of microns(5~20 μm), and that the latter is in the range of submicron(100~400 nm). The change of particle size and distribution in polymerization process were determined in miniemulsion polymerization process. It is fuond that the particle size decreased with increasing of surfactant, cosurfactant, initiator concentration, but the distribution became wider. In addition, it is bigger than convention emulsion polymerization. The changes rule of particle number and the surfactant-covering ratio were calculated. The effects of initiator and emulsifier on polymerization process and the difference of nucleation mechanism between miniemulsion and conventional emulsion were discussed.

Miniemulsion of styrene and butyl acrylate with sodium dodecyl sulfate (SDS) as surfactant and hexadecane (HDE) as cosurfactant was prepared under ultrasonification,then the miniemulsion copolymerization was carried out with a redox initiator ((NH\-4)\-2S\-2O\-8/NaHSO\-3) at lower temperature.The effects of temperature and concentrations of surfactant,cosurfactant,and initiator on the polymerization rate and conversion were determined.Under the same conditions,the polymerization rate of miniemulsion was lower than that of conventional emulsion and the initiation period was much longer.Polymerization rate increased with the increase of recreation temperature and the concentration of initiator,and surfactant.In a certain range,the polymerization rate increased with increasing HDE concentration.However,beyond that range,it decreased with increasing HDE concentration.By using computer treatment of the experimental data,a mathematical model was established for miniemulsion kinetics,then studied the kinetics characters in detail.By comparing with the results of conventional emulsion,a “monomer droplet nucleation” mechanism of miniemulsion was proposed.

If the previously prepared mixture of HDE and monomers was added to the surfactant solution, the more stable miniemulsion could be obtained. Ultrasonification was better than high speed stirring.
