Abstract
AbstractThe theory of SMITH and EWART, which describes the formation of latex particles in the emulsion polymerization system, is extended by deriving equations for the rate of change of micellar and latex particle numbers. In one case given, these equations can be integrated in closed form, but in most cases, the solutions must be found by numerical computation. The overall aim is to derive an expression for the number of reaction loci which is in terms of variables easily specified by experimental conditions – such as emulsifier and initiator content, and which predicts the number of reacting particles to be one half the total number of particles at the time when particle production ceases. This aim is attained in a limited way only, in so far as the expression sought cannot be furnished in analytic form.
