ABSTRACT:
A gas-permselective composite membrane, and a process for producing the composite membrane are described. This composite membrane comprises a heat-resistant porous polymeric membrane and a thin layer of a tertiary carbon or tertiary organic silicon-containing compound provided on one side of the membrane, the layer being prepared by polymerizing the compound by means of plasma. The membrane has highly permselective as well as superior strength and heat resistance.
