ABSTRACT:
The invention relates to an emulsion polymerization process for preparing a latex binder for use in paint. The process involves reacting a water-soluble or water-dispersible polymerizable surfactant having a terminal allyl amine moiety with at least one ethylenically unsaturated monomer and ionic monomer at a pH from about 2 to about 7. Significantly lower levels of the polymerizable surfactants are required to control the latex particle size and to stabilize the latex particles at high solids content as compared to the amount of conventional anionic surfactants used to stabilize a latex.
