A method of making a functionalized fluorinated monomer for use in making oligomers and polymers that can be used to improve surface properties of polymer-derived systems, such as coatings. The method of making a functionalized fluorinated monomer includes reacting at least one fluorinated nucleophilic reactant, such as a fluorinated alcohol, with at least one compound containing at least one epoxide group. Other methods include reaction of a fluorinated alcohol with a cyclic carboxylic anhydride. In another embodiment, a method includes reacting a fluorinated mesylate, tosylate or triflate with an amine, alkoxide or phenoxide. In other embodiments, the method includes reacting a fluorinated alcohol with an alkyl halide, or reacting a fluorinated alkyl halide with an amine. The functionalized fluorinated monomers may be used as intermediates and reacted to modify the functional groups thereon. Further, the functionalized fluorinated monomers may be reacted to form polymers or oligomers, or with polymers or oligomers having functional groups to modify the polymer or oligomer through the functional group thereon.
