COMPOSITE MEMBRANE, ITS USE AND PROCESSES FOR PERVAPORATION AND GAS SEPARATION USING THIS COMPOSITE MEMBRANE

摘要

Composite membrane, it use and processes for pervaporation and gas separation using this composite membrane A b s t r a c t A composite membrane consisting of i) a microporous membrane, containing inorganic fillers, of a film-forming thermoplastic polymer, the fillers having a specific surface area of 5200 m2/g and representing 60-90% by weight of the total weight of the membrane, and ii) a permselective elastomeric separating layer applied to the membrane, is excellently suitable for processes for pervaporation and gas separation.
