Evidence suggesting that the ultimate latex particles formed in the emulsion polymerisation of styrene are formed by the coalescence of unstable primary particles appears incompatible with the usual assumption that latex particles are predominantly n

Contrary to an earlier report, monomers (e.g.p-tert-butylstyrene and octadecyl methacrylate) which are less soluble in water than styrene have been found to polymerise in emulsion using persulphate initiation. At 60°C, the order of the Interval II p

Although a large number of methods are available for the determination of critical micelle concentrations many of these cannot be applied to the highest members of homologous series which are insufficiently soluble in water. The number of latex parti

Gardon's revision of the Smith-Ewart theory of emulsion polymerisation makes it possible to calculate the average particle size of the latex produced from the conditions used for the polymerisation at least for monomers with a low monomer transfer co

Although it has been generally accepted for the past 45 years that the latex particles which are the principal locus of the emulsion polymerization reaction are nucleated from monomer solubilized in emulsifier micelles, conclusive evidence to support

Coalescence of latex particles has generally been assumed to be negligible in emulsion polymerisations although limited coalescence has been shown to determine the number of latex particles formed in the emulsion polymerisation of the more water-solu

Using concentrations below that required to coagulate the latex, the effects of the addition of potassium chloride on the emulsion polymerization of styrene have been investigated. When potassium decanoate (an emulsifier with a high critical micelle

The problem of particle formation in aqueous solutions of vinyl acetate is treated according to the Deryaguin-Landau-Verwey-Overbeek (D.L.V.O.) theory of the stability of lyophobic colloids. In the absence of surfactants, polymer particles are stabil

Oil-soluble initiators can produce rates of emulsion polymerization similar to those obtained with the water-soluble initiators which are normally used. Although radicals are generated in pairs in the oil phase, escape of a radical to the aqueous pha
