Normally solid copolymers of a fluorinated vinyl monomer and a perfluorinated vinyl compound having a carboxyl and/or sulfonyl group attached directly to the perfluorinated vinyl group or indirectly through an alkyl or ether linkage have been found to be soluble in low molecular weight polymers of perhalogenated alkyl ethers, low molecular weight polymers of perhalogenated alkyls and perfluoro kerosenes, each of said solvent materials having boiling points between about 200. degree. C. and 350. degree. C. The copolymeric material dissolved in accordance with the instant invention can readily be resolidified by solvent removal and hydrolyzed or converted to the salt form to become a cation exchange material having an equivalent weight in the range of 1000 to 1600. When these cation exchange materials in the salt form become damaged or contaminated during operation, for example in an electrochemical cell, they may now be reclaimed rather than discarded. The process involves conversion of the salt form of the cation exchanger to the precursor sulfonyl fluoride, carbonyl fluoride, sulfonate ester, or carboxylate ester form followed by dissolution in one of the solvents mentioned above.

Polymeric connectors suitable for use in halogen lamp displays are provided. These connectors include various means for improving their reliability and heat dissipation. In specific embodiments, the electrical conductors of the connector assembly are extended beyond a polymeric connector insulator to provide convective air cooling. In other embodiments, high temperature polymers are provided which improve the heat deflection temperature of the polymeric connector insulator. Additionally, better electrical connections are made possible by more closely managed receiving cavities for lamp leads and the like.

Membrane coated cathodes can be formed using the dissolved copolymeric material and may be made by casting or coating a foraminous cathode followed by removal of the solvent to result in a continuous, pore-free coating of membrane on the cathode. Multiple coatings or other techniques can be used to build up the desired thickness of the membrane.
