Abstract

In the emulsion polymerization of polymers which comprise monomers selected from acrylic acid, methacrylic acid, alkyl esters of those acids and which may also comprise other compatible vinyl monomers such as styrene, vinyl acetate, N-methylolacrylamide, acrylonitrile, itaconic acid and the like, the emulsifier for the emulsion polymerization is a surface-active agent having the formula ##STR1## wherein ##STR2## is the acyl radical of a fatty acid having 7 to 21 carbon atoms and M is selected from ammonium, the alkali metals, and certain alkaline earth metals, and x is 1 to 3.
