Abstract
Abstract Monomers of formula I ##STR1## and/or monomers of formula II ##STR2## are used to make an emulsion for use in a latex paint. R 1 is a divalent organic radical, R 2 and R 3 are each independently selected from the group consisting of monovalent alkyl radicals containing up to about 7 carbon atoms, R 17 is a divalent organic radical, R 18 is a monovalent organic radical having an HLB value of about 17 to about 19, R 23 is selected from the group consisting of hydrogen and alkyl radicals containing up to about 5 carbon atoms, and R 24 is selected from the group consisting of hydrogen, halogen, and alkyl radicals containing up to abut 5 carbon atoms. The resulting latex paint exhibits either improved flow leveling and/or film-build.
