The comonomers are perfluorocyclic unsaturated compounds, copolymerized to form amorphous copolymer. Such copolymer forms optically clear tough coating and films.
The invention provides a polymeric composition comprising a blend of highly fluorinated ion exchange polymer and highly fluorinated nonfunctional polymer, the blend having interpenetrating continuous phases of the highly fluorinated nonfunctional polymer and the highly fluorinated ion exchange polymer. Further the invention provides for liquid compositions comprising a highly fluorinated solvent, a highly fluorinated ion exchange polymer precursor and a highly fluorinated nonfunctional polymer with the polymers being miscible with each other in the solvent. The compositions are useful for making ion exchange membranes. Membranes of the compositions have enhanced tensile properties.
