A mixed matrix membrane for gas separations is provided with a nonporous continuous phase of a polymer and a dispersed phase of molecular sieve particles reacted with a monofunctional organosilicon compound. The monofunctional organosilicon compound is characterized by (a) at least one silicon substituent group which reacts or is compatible with the polymer, and (b) at most one displaceable radical that can react with the molecular sieve. A process for making a selectively gas permeable mixed matrix membrane involves reacting a molecular sieve with the monofunctional organosilicon compound, uniformly dispersing the reacted sieve with a polymer, and forming the resulting mixed matrix composition into a membrane structure. These mixed matrix membranes provide an improved combination of permeability and selectivity as compared to polymer-only membranes and mixed matrix membranes in which the molecular sieve is not reacted with a monofunctional organosilicon compound.
