Abstract:
An acrylate, or methacrylate, or allylic, terminated oligomer, polymer, or copolymer comprising the reaction product of a) at least one polyfluorooxetane oligomer, or polymer, or copolymer polyol, b) at least one di or polyisocyanate, and c) at least one hydroxy alkyl acrylate, or hydroxy alkyl methacrylate, or hydroxy allylic, wherein either i) a) and b) are reacted to form an isocyanate terminated oligomer, or polymer, or copolymer, and said isocyanate terminated oligomer, or polymer, or copolymer is reacted with c) to form an acrylate, or methacrylate, or allylic, terminated oligomer, or polymer, or copolymer or ii) b) is reacted with c) to form an isocyanate functionalized acrylate, or methacrylate, or allylic, which is then reacted with a) to form an acrylate, or methacrylate, or allylic, terminated oligomer, or polymer, or copolymer, where said at least one polyfluorooxetane, oligomer, polymer, or copolymer polyol, comprises at least 10 weight percent repeating units of the formula where each n is the same or different and independently, is an integer between 1 and 5, R is hydrogen or an alkyl of 1 to 6 carbon atoms, and each Rf is the same or different and individually on each repeat unit is a linear or branched fluorinated alkyl of 1 to 20 carbon atoms, a minimum of 75 percent of the non-carbon atoms of the alkyl being fluorine atoms and optionally the remaining non-carbon atoms being H, I, Cl, or Br, where said acrylate, or methacrylate, or allylic terminated copolymer includes repeat units derived from tetrahydrofuran, and said acrylate, or methacrylate, or allylic, terminated oligomer, polymer, or copolymer being radiation curable.
