New fluorinated, polyfunctional propenyl ether functionalized resins were synthesized, and their behavior in cationic photopolymerization was investigated. The photopolymerization proceeded efficiently with a high double-bond conversion (>90%), giving rise to UV-cured coatings characterized by low glass-transition temperatures (−33 °C ≤ glass-transition temperature ≤ −15 °C) and hydrophobic surface properties. A fluorinated additive was also employed as a reactive additive in the cationic photopolymerization of trimethylolpropane tripropenyl ether, increasing the double-bond conversion, polymer network flexibility, thermal stability, and surface hydrophobicity.
