In emulsion polymerization, a limited degree of particle coagulation may occur. Particle coagulation is caused by a loss of colloidal stabilization when the surface coverage of emulsifier on the particles drops below a critical value. It has been demonstrated experimentally in a previous article tha

Abstract
The application of automated parallel synthesizer robots for the investigation of polymerization processes is of major interest at present. In this contribution we describe the application of the emulsion polymerization of styrene and vinyl acetate. The preparations of emulsions and latexes were investigated in detail and compared to βconventionalβ stirred tank reactors. In particular the influence of the vortex mixing as well as the limitations regarding solid content and reactor fouling are addressed.

water is usually recognized as a strong inhibitor of transition-metal polymerization. By analyzing the addition order effect of the ingredients, we show that the reduction of cobalt in the presence of butadiene is necessary for the polymerization. Radical-polymerization inhibitors such as phenols di
## Abstract It is generally admitted that the SmithβEwart equation is not applicable to the emulsion polymerization of vinyl acetate. This is considered to be due to two factors, namely, (__1__) the great solubility in water of vinyl acetate and (__2__) the fact that vinyl acetate is easily subject
