TITLE Poly(Alumino-Silicate) ABSTRACT Process for preparing particulate, porous, amorphous water-insoluble poly(alumino-silicate) having a Si/Al ratio of 2:1 to 100:1, of high surfa-e area, and in high yield, by mixing an aqueous solution of an alkali metal aluminate and an aqueous solution of silicic acid, allowing the aluminate and silicic acid in the resul-ant reaction mixture to polymerize to poly(alumino-silicate), and thereafter removing sufficient water from the reaction mixture to permit recovery of the particulate poly(alumino-silicate) therefrom; and particulate poly(alumino-silicate) prepared thereby.
