ABSTRACT:
Highly monodisperse latexes of non-film forming polymers are prepared by (1) dispersing a hard monomer and an ethylenically unsaturated amide in an aqueous medium containing a surfactant in an amount less than the critical micelle concentration of the surfactant and (2) subjecting the dispersion to emulsion polymerization. Such monodisperse latexes are useful as opacifying pigments in paper coatings, as internal calibration standards in electron microscopy, and as model systems for study of colloidal properties.
