Abstract
Abstract A water insoluble emulsion polymer used as a component of floor finish formulations. The polymer comprises the emulsion polymerization reaction product of from about 5 to about 40% by weight alpha methylstyrene, from about 5 to about 40% by weight styrene and about 60% of other monoethylenically unsaturated monomers such as, for example, acrylic acid, methacrylic acid and their esters, said weights being based on the combined weight of monomers charged. The emulsion polymer is combined with an alkali soluble resin and a natural or synthetic wax to provide an emulsion floor finish product which may be of the buffable or of the self-polishing kind. The final floor finish product is an aqueous emulsion containing 8 to 45% by weight solids and preferably 10 to 20% by weight solids.
