Abstract
Fluorinated polymers having epoxy resin structure, containing at least 10% by weight, preferably 20% by weight, of fluorine, prepared starting from epichlorohydrin and from one or more diols, at least one of which is a perfluoroalkylene diol, and by using conventional cross-linking agents for epoxy resins, such as anhydrides of dicarboxylic acids, di- or tri-isocyanates, polyfunctional amines.
