摘要： The invention concerns a membrane for selective gas separation. The membrane consists of an ethylene oxide copolymer or a polymeric material obtained by crosslinking such a copolymer. Said copolymer is characterised in that it consists of at least 30 % in number of -CH2CH2O- units derived from ethylene oxide, and at least 2 % in number of -CHR-CH2O- units derived from an oxirane bearing a crosslinkable substituent R and/or of -CHR1-CH2O- units derived from an oxirane bearing a non-crosslinkable substituent R1. The membranes are particularly useful for separating hydrophilic gases contained in a gas mixture.

摘要： A process for preparing a polyether ether ketone membrane usable as ultrafilter or microfilter at high temperature. This process comprises dissolving a polyether ether ketone in a solvent, casting the resulting stock solution for membrane formation into a desired shape, and bringing the cast material into contact with a solidifying medium for polyether ether ketone to form a non-sulfonated polyether ether ketone membrane, and is characterized in that concentrated sulfuric acid is used as the solvent and the stock solution is kept at a temperature of 15 °C or below until the beginning of membrane formation.

摘要： A method is provided for making crosslinked acidic polymers useful as ion conductive membranes, such as crosslinked sulfonated polyether ketones, sulfonated polysulfones, sulfonated polystyrenes, and other acidic polymers, by crosslinking with a species which generates an acidic functionality. The crosslinker preferably binds to acid functions by conversion of acid groups to imide functinality, which, due to the acidity of the N-H bonds therein, compensate for the acidity lost by the occupation of the acid groups and thus preserve membrane conductivity while contributing to membrane strength and resistance to swelling.
