Carbon molecular sieve (CMS) membranes were prepared by pyrolysis of polyimides containing carboxylic acid groups, in order to investigate their permeation properties for He, CO 2 , O 2 and N 2 . The polyimides were synthesized with a varying number of carboxylic acid groups in the diamine. Wide-ang

High molecular weight PPO was brominated to three levels of degree of bromination. Each brominated PPO was further sulfonated to three levels of degree of sulfonation. Membranes were prepared from these sulfonated brominated PPO (SPPOBr) and the transport properties of CO 2 , CH 4 , O 2 , and N 2 ga

One of the common polyimides, benzophenone tetracarboxylic dianhydride (BTDA)-4,4 -oxydianiline (ODA) polyimide, containing a ketone bridging group was synthesized to study the structural characteristics of the role of the polyimide on the properties of nanoporous carbon molecular sieve (CMS) membra
