Abstract
For use as an emulsifier for emulsion polymerization of acrylate monomer mixtures, there is provided a novel mixture of soluble salts of sulfosuccinate half esters of two or three alcohols, each selected from a different class defined and each respective half ester being present in a defined range of proportions in the mixture. The defined emulsifiers, even when used at concentrations less than usual for emulsion polymerization, produce acrylate latex products having a favorable combination of several advantageous properties, particularly good mechanical stability and low viscosity, even when a cross-linking monomer is included in the monomer mixture to be polymerized.
