By using glycidyl methacrylate, methacrylate and 2,2,3,4,4,4-hexafluorobutyl methacrylate as monomers, a series of binary and ternary cationic ultraviolet (UV)-curable copolymers were synthesized, and their structures were characterized. These copolymers were coated on glass substrates and cured with an epoxy siloxane under UV irradiation, and the contact angle, chemical ability, gloss, light transmittance, as well as thermal degradation on set temperature of the cured films were determined. The results indicated that the cured coatings showed more than 80% gloss and more than 85% visible light transmittance. The ternary copolymers showed relatively high stability if immersed in water and if immersed in acidic and basic solutions. The observed higher stability was considered as a result of the highly stable chemical structure of the terpolymer and of the presence of fluorinated- and siloxane-containing moieties.
