Title: Compatibilized immiscible polymer blends and molecular sieve membranes thereof

Abstract

In some aspects, the present disclosure provides a polymer composition which comprises two polymer molecules and a compatibilizing agent. In some embodiments, the polymer composition is useful for the preparation of membranes used in the separation of two or more gases. In some embodiments, the polymer composition comprises a polyimide polymer and a polybenzimidazole polymer which have been compatibilizing with a small molecule or a metal organic framework.
