    摘要: The present invention provides a high selectivity epoxysilicone-cross-linked polyimide membrane comprising a polyimide polymer with hydroxyl functional groups cross-linked with epoxy functional groups on epoxysilicone polymer. The present invention also provides a process for separating at least one gas from a mixture of gases using the high selectivity epoxysilicone-cross-linked polyimide membrane. The process comprises providing the high selectivity epoxysilicone-cross-linked polyimide membrane which is permeable to the at least one gas; contacting the mixture on one side of the membrane to cause the at least one gas to permeate the membrane; and removing from the opposite side of the membrane a permeate gas composition comprising a portion of the at least one gas which permeated the high selectivity epoxysilicone-cross-linked polyimide membrane.

    摘要: A copolyimide polymer membrane is provided for separation of hydrocarbons including separation of olefins from paraffins and isoparaffins from other paraffins. The copolyimide polymer membranes include a poly(3,3′-diaminobenzophenone-3,3′,5,5′-tetramethyl-4,4′-methylene dianiline-pyromellitic dianhydride) (abbreviated as poly(DAB-TMMDA-PMDA)). The copolyimide membranes prepared from poly(DAB-TMMDA-PMDA) with varying molar ratios of DAB to TMMDA (abbreviated as PI-DAB-T) showed excellent separation properties for propylene/propane separation.

    摘要: Cross-linked rubbery polyurethane-ether polymeric membranes are made from cross-linked rubbery polyurethane-ether polymers that are synthesized from a diisocyanate-terminated polyether and a tetrol with four hydroxyl functional groups. The hydroxyl groups on the tetrol react with the isocyanate groups on the diisocyanate-terminated polyether to form urethane bonds. The cross-linked rubbery polyurethane-ether polymeric membrane selectively permeate condensable vapors such as C3 to C35 hydrocarbons, aromatics, water vapor, carbon dioxide, and hydrogen sulfide and rejects methane and ethane. The cross-linked rubbery polyurethane-ether polymeric membrane have high permeance for condensable vapors, high selectivity for condensable vapors over methane and ethane, and high resistance to liquid chemicals.

    摘要: The present invention discloses new types of poly(amidoamine) (PAMAM) dendrimer-cross-linked polyimide membranes and methods for making and using these membranes. The membranes are prepared by cross-linking of asymmetric aromatic polyimide membranes using a PAMAM dendrimer as the cross-linking agent. The PAMAM-cross-linked polyimide membranes showed significantly improved selectivities for CO2/CH4 compared to a comparable uncrosslinked polyimide membrane. For example, PAMAM 0.0 dendrimer-cross-linked asymmetric flat sheet poly(3,3′,4,4′-diphenylsulfone tetracarboxylic dianhydride-3,3′,5,5′-tetramethyl-4,4′-methylene dianiline) (DSDA-TMMDA) polyimide membrane showed CO2 permeance of 135.2 A.U. and CO2/CH4 selectivity of 20.3. However, the un-cross-linked DSDA-TMMDA asymmetric flat sheet membrane showed much lower CO2/CH4 selectivity (16.5) and higher CO2 permeance (230.8 GPU).
