Random-design for the Technology of Emulsion Polymerization with High Solid Content and the Statistical Analysis of the Resultant Data

Anovel randomly-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, butyl acrylate (BA), and acrylic acid, six principal factors were chosen for random-design process. Then, regression analysis was used for the random-design experimental results by a known statistical analysis system (SAS). In turn, the optimal regression equations were established between the principal factors and the emulsion properties. It is shown that the particle size and size distribution are greatly affected by the following factors: the square values of the solid and emulsifier contents and the interactions between the initiator concentration and functional monomer concentration, BA concentration and reaction temperature, emulsifier content and reaction temperature, solid content and reaction temperature, and SA and functional monomers.
