Abstract: 1,199,668. Ion - exchange membranes. RHONE-POULENC S.A. 24 Sept., 1968 [25 Sept., 1967], No. 45369/68. Headings C3G and C3P. [Also in Divisions D1-D2] An ion-exchange membrane is formed of a vinyl chloride polymer or copolymer grafted with an aromatic vinyl monomer comprising an intranuclear or juxtanuclear tertiary nitrogen atom, or of a mixture of a vinyl chloride polymer or copolymer and a polymer of an aromatic vinyl monomer comprising an intranuclear or juxtanuclear tertiary nitrogen atom, all or part of the said tertiary nitrogen atoms having been quaternized by an alkylene or alkenylene dihalide or bis-(haloalkyl)-benzene. Specified aromatic vinyl monomers are vinyl pyridines and N,N-dialkylaminostyrenes. The polymer may be partially quaternized with the dihalide and the quaternization completed using a monofunctional quaternizing agent, e.g. an alkyl, cycloalkyl or aralkyl halide or sulphate. In the examples, (1) polyvinyl chloride is grafted with 4-vinylpyridine, the resulting graft polymer being quaternized with p-dodecylbenzyl chloride and bis - 1,4 - (chloromethyl) - benzene then treated with methyl iodide, (2) a membrane is formed as in Example 1, except that no dodecylbenzyl chloride is used, (3) a polyethylene glycol terephthalate fabric is soaked in a solution of the graft copolymer obtained in Example 1 and the supported film obtained is quaternized as in Example 1, (4) a solution of polyvinyl chloride and p-dimethylamino-styrene in cyclohexanone is poured on to glass, dried and then quaternized as in Example 2, (5) and (7) polyvinyl chloride and poly-p-dimethylaminostyrene are dissolved in cyclohexanone and a film formed from the solution is quaternized as in Example 2 and (6) a membrane reinforced with fabric is formed as in Example 3, using the solution of polymers prepared in Example 5.

Abstract: 1,220,776. Cation exchange membranes. RHONE - POULENC S.A. 29 April, 1969 [29 April, 1968], No. 21897/69. Heading C3P. [Also in Division B1] A cation exchange membrane made of a homogeneous mixture of (a) a poly-p-vinylphenol, which is optionally halogenated, and which is cross-linked via the oxygen atoms of its hydroxyl groups and substituted by cation exchange radicals, and (b) an inert polymer may be prepared by forming a layer of a solution in and organic solvent of the inert polymer and the poly-p-vinylphenol and then, either successively or simultaneously, evaporating the solvent, cross-linking the poly-p-vinylphenol by reaction with its hydroxyl groups and introducing the cation exchange radicals. The inert polymer is one which does not interfere with the cross-linking of the poly-p-vinylphenol or the introducton of cation-exchange radicals and in particular is inert to halogenated compounds and sultones. Suitable polymers are polyvinyl chloride and a copolymer of vinyl chloride with vinylidene chloride or vinyl acetate. Cross-linking may be effected by dehydration in an inert medium containing hexamethylphosphotriamide or dioxane or by treatment of the salt of the polymer with a compound containing at least two reactive halogen atoms e.g. o- or p-xylylene dihalide or 3,3 - bis(halogeno - methyl) - oxetane. Crosslinking and radical introduction may be effected by reaction with a polysultone e.g. spirobi-2: 2 1 - propanesultone. Exchange radicals may be introduced by sulphonation with e.g. sulphuric acid, oleum, chlorosulphonic acid or a monosultone e.g. propanesultone. The membrane may also contain a quaternary ammonium salt and a hexaalkyl phosphotriamide. In the examples are also used poly(4 - hydroxy - 3 - chlorostyrene), poly(4 - hydroxy - 3 - bromostyrene), methyltrilaurylammonium chloride and tributyl orthophosphate.

Abstract: 1338543 Electro-phoresis of blood RHONEPOULENC S A 28 March 1972 [30 March 1971] 14459/72 Heading C7B [Also in Division A5] A method for the continuous fractionation of an aqueous liquid containing at least two compounds, the mobilities of which is an electric field vary as a function of the pH, comprises introducing the liquid into an electro-phoresis cell in contact with one face of a filtering membrane, applying an electric field between two electrodes located on either side of the membrane, forcing a fraction of the liquid to pass across the membrane to provide a filtered portion and of removing separately the filtered portion and the unfiltered remaining portion of the liquid; causing a stream of main electrolyte independent of the liquid to be fractionated, to flow in contact with each electrode and causing two streams of auxiliary electrolyte to flow between dialysis membranes which are permiable to ions, said dialysis membranes separating each auxiliary electrolyte stream firstly from the stream of main electrolyte and secondly from the filtered portion of liquid and from the unfiltered removing portion of the liquid respectively, the two streams of auxiliary electrolyte having different average pH between their introduction and removal from the cell. The forced flow electro-phoresis cell 1 is divided into six compartments. The liquid to be treated is passed into compartment 5 where it is subjected to hydrostatic pressure. Part of the liquid filters through membrane 12 and leaves the cell via orifice 21. The unfiltered part leaves through orifice 20. Main electrolyte is introduced simultaneously via orifices 15 and 24 to the anode and cathode compartments 2 and 8 and is removed via orifices 16 and 25. The two portions of main electrolyte are combined in tank 26 and are recirculated. Auxiliary electrolyte is introduced via orifices 17 and 22 into intermediate compartments 4 and 7 and is removed via orifices 18 and 23. The two portions of auxiliary electrolyte are combined in tank 29 and are recycled. The cell temperature is controlled by thermostat 45. The reactant controlling the pH of the auxiliary electrolyte is introduced into tank 29. The electrodes may be stainless steel mesh. The dialysis membranes 11 and 13 may be permeable to ions and molecules M.W.

Abstract: 1,218,677. Ionically conductive resins. KHONE-POULENC S.A. 11 April, 1969 [12 April, 1968], No. 18819/69. Headings C3G and C3P. A cross-linked, ionically conductive resin containing both sulphonic groups and quaternary nitrogen atoms is prepared by reacting one or more polysultones with a polymer containing in each molecule a plurality of tertiary nitrogen atoms. The preferred polysultone is the di-γ- sultone of 2,2-bis-(hydroxymethyl)-propane-1,3- disulphonic acid. The tertiary nitrogen atomcontaining polymer may be a polymer of vinyl pyridine, a dialkylaminovinylbenzene or a dialkylaminoalkylvinylbenzene, or a polymer grafted with a tertiary nitrogen atomcontaining monomer. An inert polymer may be included in the reaction mixture, e.g. a vinyl chloride polymer. Remaining tertiary nitrogen atoms on the polymer may be quaternized with a monosultone, e.g. propanesultone. In the examples films of the resins are cast using polyvinyl chloride, poly-para-dimethylaminostyrene, cyclohexanone, spirobi - 2: 2 1 - propanesultone, hexamethylphosphotriamide, propanesultone, dibutyl ether, squalene, xylene, polyvinyl chloride/4-vinyl-pyridine graft copolymer, pyridine and isobutanol.
