ABSTRACT:
Asymmetric polymeric gas separation membranes comprise amorphous aryl substituted arylene oxide polymer. Such amorphous polymer is capable of forming hollow fiber membranes by wet spinning procedures utilizing coagulation baths and bore injection fluids comprising water. Desirable aryl substituents include halogens, nitro, lower alkyls and lower acyls.
