Abstract
Latex particles of ethyl acrylate-methacrylic acid copolymers prepared by semicontinuous emulsion polymerization with a monomer emulsion fee d were found to disintegrate into smaller subparticles on alkalization . This phenomenon observed by light scattering and scanning electron m icroscopy is explained in terms of heterogeneous structure of latex pa rticles which are agglomerates of small particles formed by coagulatio n during polymerization. The influence of particle size and polymeriza tion route on particle heterogeneity is discussed.
