✦ Synopsis

Abstract

The effects of comonomer composition and the method of monomer addition on the compositional homogeneity and the colloidal properties of (vinyl acetate‐butyl acrylate) copolymer latexes were investigated. Particle size and distribution, and the surface characteristics of the copolymer latexes were found to vary with the comonomer composition and the type of the polymerization process. The aging of the latexes affects the surface properties and by that the colloidal stability against electrolytes. Branching, hydrolysis, flexibility of the molecules and heterogeneity of the latex particles appear to play a major role for the stability of the latexes.
