Abstract:
A coating composition comprising;a functionalized polyfluorooxetane oligomer, or polymer, or copolymer, with at least 10 weight percent repeating units of the formula: or combinations thereof, where n is the same or different and independently 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 independently 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; said functionalized copolymer being derived from a comonomer having an epoxy (oxirane) functionality, a monomer having a 4-membered cyclic ether group, a monomer having a 5-membered cyclic ether group, 1,4-dioxane, 1,3-dioxane, 1,3-dioxalane, trioxane, or caprolactone, or combinations thereof;at least one unsaturated comonomer copolymerizable with said functionalized oligomer, or polymer, or copolymer; optionally a free radical initiator which is activated by ultraviolet radiation, and optionally a crosslinking agent.
