This invention concerns a process for production of copolymers, especially functionalized, or, at least partially fluorinated copolymers by means of a polymerization process comprising: co-polymerizing, in aqueous emulsion, one or more monomers selected from the group consisting of tetrafluoroethylene, trifluoroethylene, vinylidene fluoride, vinyl fluoride, ethylene, chorotrifluoroethylene, hexafluoropropylene, perfluoromethyl vinyl ether, and perfluoroethyl vinyl ether with a fluorinated co-monomer having limited water solubility, said comonomer being dispersed in the form of droplets of certain sizes.

This invention concerns a method for forming ionomers by treatment with ammonium carbonate of copolymers having a substantially fluorinated, but not perfluorinated, polyethylene backbone having pendant groups of fluoroalkoxy sulfonyl fluoride. Ionomers derived therefrom by ion exchange are useful in electrochemical applications such as batteries, fuel cells, electrolysis cells, ion exchange membranes, sensors, electrochemical capacitors, and modified electrodes.

Optical articles, such as displays, optical lenses, windows, optical polarizers and transparent films are made as a composite structure comprising a substrate and an anti-reflective coating applied to the substrate. The anti-reflective coating comprises: A) a fluoroelastomer having cures sites selected from the group consisting of bromine atoms, chlorine atoms, iodine atoms, non-conjugated dienes, and mixtures of two or more thereof; and B) a non-fluorinated multiolefinic cross linking agent. The surface of the substrate may be treated by simultaneously bombarding the surface with an ionized inert gas, and etching the surface with an ionized reactive gas, so as to improve the adhesion of the coating to the substrate.
