AROMATIC POLYETHERKETONE GAS SEPARATION MEMBRANES

摘要

TITLE AROMATIC POLYETHERKETONE GAS SEPARATION MEMBRANES Novel substituted aromatic polyetherketone gas separation membranes and the process of using such membranes to separate one or more gases from a gaseous mixture is disclosed. The polyetherketones are formed from aromatic alcohols of the formula <IMG> where Z is independently alkyl groups having 1 to 10 carbon atoms, most preferably a tertiary butyl group, n is an integer from 1 to 4, preferably 1.
