Abstract
A stable aqueous polymer emulsion contains an aqueous continuous phase, a dispersed polymeric phase which comprises an acrylic polymer and a polyhydroxyl functional, non-ionic surfactant having a repeating polymer unit in the backbone and containing from 3 to 31 hydroxyl groups wherein the hydroxyl groups on the repeating polymer unit are separated by 4 or more carbon atoms and the surfactant is substantially free of oxyethylene units.
