FLUORINATED POLYMERS AND RESINS PREPARED THEREFROM

摘要

New resins containing urethane and/or epoxy bonds are prepared starting from fluorinated polymers having an epoxy structure and exhibiting structural characteristics predominantly typical of epoxides or of polyols, said polymers being prepared by synthesis from one or more diols, at least one of which being a perfluoropolyoxyalkylene diol, and from epichlorohydrin; said polymers are subsequently subjected to a treatment with isocyanated if their structural characteristics are predominantly those of polyols, or with polyamines or anhydrides if their structural characteristics are predominantly those of epoxides.
