Abstract
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 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.
