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.
