Abstract
Monofunctional polyfluorooxetane oligomers and polymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. The fluorooxetane oligomers or polymers can be copolymerized with generally cyclic ethers. Alternatively, the polyfluorooxetane oligomer or polymer having a single hydroxyl end group can be functionalized with a variety of compounds so as to yield a functional end group such as an acrylate, a methacrylate, an allylic, an amine, etc., with the functionalized oligomer or polymer being suitable for use in radiation curable or thermal curable coating compositions. These functionalized polymers can be copolymerized and cured to provide improvements in wetting and surface properties that have previously been provided by migratory chemicals such as waxes and oils. The partially or fully fluorinated side groups of the fluorooxetanes are believed to be disproportionately present at the interfaces between the coating and the substrate and between the coating and the atmosphere.
