ABSTRACT:
An aqueous emulsion for use as a water- and oil-repellent agent, which aqueous emulsion is produced by copolymerizing least one of lower alkyl methacrylate, benzyl (meth)acrylate and vinylidene chloride with polyfluoroalkyl group-containing (meth)acrylate ester, dispersed in water and in the presence of a nonionic emulsifier containing .alpha.-[1-(allyloxy)methyl-2-(p-nonylphenoxy)ethyl]-.omega.-hydroxy(polyo xyethylene). The resulting aqueous emulsion is completely free from organic solvents and has a distinguishing freeze-thaw stability.
