Abstract

An oxygen permeable polymer has the following formula: wherein R S is a non-sulfonyl halide portion of a sulfonyl halide monomer or polymer; X P is —NH or —NHCO; A is an optionally substituted alkyl; L is 0, 1 or 2; m is 2 or 3; Z is H or CH 3 ; and n is 5-m. The polymer can be used in air separation devices, air concentrators, and in electrodes for electrochemical devices.
