Abstract
Disclosed is a process for preparing a membranous gas separator comprising (a) a porous substrate having an average pore diameter of not greater than 100 .ANG. and (b) a .pi.-electron conjugated conducting polymer retained within at least a part of the pores of the porous substrate in such a way that the pores are not blocked, characterized in that retaining the .pi.-electron conjugated conducting polymer within the pore is carried out by a chemical oxidative polymerization.
