    摘要： Latex paint compositions containing water, pigment and a latex wherein the latex is prepared by emulsion polymerization of at least one ethylenically unsaturated monomer in the presence of 0.1 to 0.2 pphm of at least one hydrophobically modified starch having the structure ##STR1## In the above structure, St is a starch base material, R.sup.1 is a dimethylene or trimethylene group, R.sup.2 is selected from the group consisting of alkyl, alkenyl, aralkyl and aralkenyl groups having 2 to 20 carbon atoms, and Y is selected from the group consisting of hydrogen, alkali metal, alkaline earth metal and ammonium. The hydrophobically modified starch is the reaction product of starch and an anhydride moiety and provides the latex paint with improved rheological properties and allows for easier spreading and less dripping of paint.

    摘要： 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.
