Anionic waterborne polyurethane dispersions are formed in the presence of polyfluorooxetane oligomers, polymers, or copolymers so that the polyfluorooxetanes are incorporated in the polyurethane. Coatings made from such polyurethanes have good low temperature flexibility, good chemical resistance, stain resistance, and abrasion resistance, as well as a low coefficient of friction. Alternatively, the anionic water borne polyurethane dispersion can be blended with vinyl ester monomers such as various acrylates and subsequently polymerized by radiation, for example ultraviolet light, to form a comingled blend of at least two different types of polymers. Another embodiment relates to a preformed copolymer made by reacting the polyfluorooxetane oligomer, polymer, or copolymer with a polycarboxylic acid such as a dicarboxylic acid and subsequently reacting the same with a polyol intermediate, such as a polymer, or with monomers forming the polyol intermediate.
