| 摘要 |
Novel permselective membrane compositions comprise a crosslinked polymer membrane. The polymer membrane has from about 25 to 100 parts by weight of a polyarylene having the formula <IMAGE> and from about 0 to 75 parts by weight of a crosslinkable copolymer, the copolymer being present at least when the polyarylene component is devoid of crosslinkable cites. The foregoing polymer or polymer mixture is crosslinked by a silicon-containing amineterminated compound selected from the group consisting of the siloxanes having the formula <IMAGE> and silanes having the formula H2N-R2-[Si-O-R4]3. A process is provided for the separation of gases from a mixture containing at least two gases and includes the step of passing the gas mixture over the permselective membrane composition of the present invention.
