Resins containing urethane and/or epoxy bonds which are useful as adhesives, structural materials paints and coatings, are prepared starting from fluorinated polymers and having an epoxy structure and exhibiting structural characteristics prevailingly typical of epoxides or of polyols. The polymers are prepared by synthesis from one or more diols, at least one of which is a perfluoropolyoxyalkylene diol and from epi-, chlorohydrin. The polymers are subsequently subjected to a treatment with isocyanated if their structural characteristics are prevailingly those of polyols or, with polyamines or anhydrides if their structural characteristics are prevailingly those of epoxides.
