The Effect of the Size of the Initial Micelles on the Nucleation of Latex Particles in the Emulsion Polymerization of Styrene

Summary

The effect of the homologous series of alkyl sulphates (C8 - C18) and alkyl carboxylates (C8 - C22) in the emulsion poly merization has been investigated. Micellar nucleation of latex particles is predominant in the styrene emulsion polymerization and it is found that it is the concentration of micellar surfactant which determines the number of latex particles formed and hence the rate of polymerization. Equal concentrations of micellar emulsifier give equal numbers of latex particles with the same particle size distribution and the same Interval II polymerization rate although the duration of Interval I during which particle formation is taking place may vary. The surface area of the original micelles appears to be the factor which determines the number of latex particles ultimately formed.
