    Abstract: This invention is directed to the preparation of an organic-inorganic composite body demonstrating hydrophobic behavior containing crystals of an organic polycation-exchanged lithium and/or sodium water-swelling mica, the organic polycation being selected from the group of aminosilanes and organic chrome complexes. The process of preparing such products contemplates the steps of:(a) forming a glass-ceramic body containing crystals selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolylithionite, phlogopite, and fluorphlogopite;(b) contacting said body with a polar liquid for a time sufficient to cause swelling and disintegration thereof accompanied with the formation of a gel; and(c) contacting said gel with a source of organic polycations selected from the group of aminosilanes and chrome complexes to cause an ion exchange reaction to occur between said polycations and the Li.sup.+ and/or Na.sup.+ ions from the interlayer of said crystals, whereby essentially all of said Li.sup.+ and/or Na.sup.+ ions are replaced with said organic polycations.Paper, board, film, fiber, and coating can be formed from the exchanged gel, and dried powders thereof can be hot pressed to yield a body consisting of a cross-linked organic polycation-mica derivative.

    Abstract: The present invention is founded upon the fundamental discovery that anhydrous silicate materials can be formed into solid bodies which are hydrated or wherein the silicate structure is depolymerized by protonic reagents other than water. Such bodies can be produced by compression molding the anhydrous silicate material with water or other protonic reagent at elevated temperatures and high pressures.

    Abstract: This invention relates to the coprocessing of hydrated glass with organic polymers to form integral bodies which can be stronger, tougher, and more durable than the original hydrated glass and stiffer than the original plastic material. The process is amenable to any hydrated glass so long as the processing temperature of the hydrated glass is below the temperature at which decomposition of the organic polymer takes place. Chemical bonding between the hydrated glass and a thermosetting organic polymer is achieved through the use of silane coupling agents. Such are not necessary with thermoplastic polymers. The invention is applicable with both thermosetting and thermoplastic polymers which are resistant to alkali environments.
