The present invention discloses a novel method of making high performance mixed matrix membranes (MMMs) using stabilized concentrated suspensions of solvents, uniformly dispersed polymer stabilized molecular sieves, and at least two different types of polymers as the continuous blend polymer matrix. MMMs as dense films or asymmetric flat sheet or hollow fiber membranes fabricated by the method described in the current invention exhibit significantly enhanced permeation performance for separations over the polymer membranes made from the continuous blend ...
What is claimed is: 1. A process for separating at least one gas from a mixture of gases comprising:a) providing a mixed matrix gas separation membrane comprising a polymer stabilized molecular sieves approximately uniformly dispersed in a continuous polymer matrix phase comprising at least two different polymers wherein said continuous polymer matrix is permeable to at least one gas in said mixture of gases wherein said polymer stabilized molecular sieves are stabilized by at least one polymer selected from the group consisting of polyethersulfones, sul...
