| This invention relates to a process for the preparation of silicious polymeric materials and their use in the separation of fluids in the gaseous phase, wherein the materials are obtained through three basic procedures: (a) polymerization of monomeric substances in the presence of high purity submicroscopic silica particles in which the polymerization of the monomers can be followed by a deactivation reaction with silylating agent; (b) addition of high purity submicroscopic silica particles to monomeric substances, and coupling regents, which will react with surface hydroxyl groups on the silica and a polymer or monomers which are forming a polymer in the reaction medium; (c) through dispersion of the high purity submicroscopic particles in plymeric organic substances. The materials obtained in this invention are solid, usually white, highly porous, of relatively high surface area, thermally stable and have good mechanical strength, and when used as a packing material in a gas chromatographic column provide excellent results with respect to permeability, efficiency, and selectivity. | ||||||
