Neutralized polyelectrolyte complexes exhibiting hydrophobic behavior containing crystals of an organic polycation exchanged lithium and or sodium water-swelling mica are made by:-… (1) forming a glass-ceramic body containing crystals selected from fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from talc, fluortalc, polylithionite, fluropolylithionite, phlogopite, and fluorphlogopite;… (2) contacting that body with a polar liquid to cause swelling and disintegration of the body accompanied with the formation of a gel; and… (3) contacting said gel with a source of organic polycations to cause a reaction between the Li<+> and/or Na<+> ions from the interlayer of the crystals and to neutralize the charge density of the crystals, thereby forming a neutralized polyelectrolyte complex. …<??>The complex may be formed into paper, board, film, fiber or coating by dispersion of the complex into a selected liquid and forming the paper, board, film or coating from such dispersion. |
