    • 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.
    • 单官能聚氟乙烯低聚物和聚合物是通过氟代氧杂环丁烷单体与一元醇的阳离子聚合制备的。 氟氧杂环丁烷低聚物或聚合物可以与通常的环醚共聚。 或者,具有单个羟基端基的多氟氧杂环丁烷低聚物或聚合物可以用各种化合物进行官能化,以产生官能化低聚物等丙烯酸酯,甲基丙烯酸酯,烯丙基胺,胺等功能性端基 或聚合物适用于可辐射固化或热固化涂料组合物。 这些官能化聚合物可以共聚和固化,以提供以前由迁移的化学品如蜡和油提供的润湿和表面性能的改进。 认为氟氧杂环丁烷的部分或完全氟化的侧基不成比例地存在于涂层和基底之间以及涂层和大气之间的界面处。
