ABSTRACT:
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 ##STR1## 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 ##STR2## and silanes having the formula
