Abstract
Des copolymeres normalement solides d'un monomere de vinyle fluore et d'un compose de vinyle perfluore ayant un groupe carboxyle et/ou sulfonyl attache directement au groupe de vinyle perfluore ou indirectement par l'intermediaire d'une liaison alkyle ou ether se sont reveles etre solubles dans des polymeres de faible poids moleculaire d'ethers d'alkyle perhalogenes, dans des polymeres de faible poids moleculaire d'alkyles perhalogenes et de perfluoro kerosenes, chacun de ces materiaux solvants ayant des points d'ebullition situes entre 200 C et 350 C environ. Le materiau copolymere dissous selon la presente invention peut etre facilement resolidifie par extraction du solvant et hydrolyses ou convertis sous la forme d'un sel pour devenir un materiau d'echange cationique ayant un poids equivalent compris entre 1000 et 1600. Des cathodes revetues d'une membrane peuvent etre formees en utilisant un materiau copolymere dissous et peuvent etre fabriquees en coulant ou en enrobant une cathode foraminee, puis en extrayant le solvant pour obtenir un enrobage continu de membrane, sans pore sur la cathode. De nombreux revetements ou d'autres techniques peuvent etre utilisees pour former l'epaisseur desiree de la membrane. Une membrane renforcee peut etre produite par des techniques de fabrication semblables ou le coulage ou l'enrobage de la membrane s'effectue sur une toile de support de renforcement qui peut etre une maille en polytetrafluoroethylene ou autre avec laquelle on entoure la cathode foraminee. Le materiau copolymere qui est utilise dans la fabrication d'une cathode revetue d'une membrane peut etre un materiau simple ou des structures, poids divers equivalents (carboxyle ou sulfonyl, des melanges de ceux-ci, ou des couches de materiaux identiques ou differents).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 bond have been found be soluble in low molecular weight polymers of perhalogenated alkyl ethers, in low molecular weight polymers of perhalogenic alkyls and perfluoro kerosenes, each of these solvent materials having boiling points between 200 C and 350 C approx. The dissolved copolymer material according to the present invention can be easily resolidified by extraction of the solvent and hydrolyzed or converted in the form of a salt to become a cation exchange material having an equivalent weight of between 1000 and 1600. Cathodes coated with a membrane can be formed using a dissolved copolymer material and can be made by casting or coating a foramine cathode, then extracting the solvent to obtain a continuous, pore-free membrane coating on the cathode. Many coatings or other techniques can be used to form the desired thickness of the membrane. A reinforced membrane can be produced by similar manufacturing techniques or the casting or coating of the membrane is carried out on a reinforcing support fabric which can be a polytetrafluoroethylene mesh or the like with which the foramine cathode is surrounded. The copolymer material which is used in the manufacture of a cathode coated with a membrane can be a simple material or structures, various equivalent weights (carboxyl or sulfonyl, mixtures thereof, or layers of identical or different materials ).
