Abstract
Described is a compound having at least one acrylate monomer, said monomer including at least one pendant group of the structure —O—CH(Rf)(Rf′), wherein Rf is a straight chain or branched perfluoroalkyl group with five or less carbon atoms, and Rf′ is a branched perfluoroalkyl group with three to five carbon atoms; and a method of reducing the surface tension of a liquid by adding a compound of the invention to the liquid. Also described is a composition that includes a compound of the invention in an aqueous solution or dispersion; a method of treating a substrate to render it oil- and/or water-repellent that includes treating a substrate with a composition of the invention; a method of coating an electrical device that includes applying a composition of the invention; a method of coating optical fibers that includes applying a composition of the invention; and an article that includes a substrate treated with a composition of the invention.
