Patent number: 6673889Abstract: Acrylate, or methacrylate, or allylic, functionalized polyfluorooxetanes are disclosed for use in radiation curable coating compositions. These acrylate, or methacrylate, or allylic, functionalized polymers 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.Type: GrantFiled: September 16, 1999Date of Patent: January 6, 2004Assignee: Omnova Solutions Inc.Inventors: Raymond J. Weinert, Guillermina C. Garcia, James E. Robbins, Aslam Malik

Publication number: 20030208015Abstract: Monofunctional polyfluorooxetane oligomers, polymers, and copolymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. In addition to serving as an initiator, the monoalcohol can also serve as a solvent for the fluorooxetane or other monomers to produce oligomers, polymers, or copolymers having low cyclic content. Suitable comonomers generally include various cyclic ethers. The polyfluorooxetane oligomer, polymer, or copolymer 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.Type: ApplicationFiled: December 1, 2000Publication date: November 6, 2003Inventors: Robert Medsker, Gary L. Jialanella, Raymond J. Weinert, Guillermina C. Garcia, Aslam Malik, Roland Carlson
