A novel random-arranged experimental design method (“random-design”) was employed to optimize the technology of emulsion polymerization with high solid content. In the case of the emulsion copolymerization of styrene (St), butyl acetate (BA) and acrylic acid (AA), six principal factors were chosen for random-design process. The random-designed experimental results were then made regression analysis with the known statistical analysis system (SAS), and the optimal regression equations between the principal factors and the emulsion properties were in turn established. It is exhibited that the square value of solid content, the interaction between the initiator concentration and functional monomer concentration, the square value of emulsifier content, the interaction between BA concentration and reaction temperature, the interaction between emulsifier content and reaction temperature, the interaction between solid content and reaction temperature, the interaction between the concentrations of initiator, BA and functional monomer, all greatly affect the particle size.
