ABSTRACT:
In a process for preparing particulate, porous, water-insoluble amorphous poly(alumino-silicate) having a Si/Al gram-atomic ratio of about 1:1 to 10:1, a pore volume of greater than 0.5 ml/g, an average pore diameter of 50 to 200 A and a surface area of 200 to 600 m.sup.2 /g by mixing an aqueous solution of an appropriate aluminate and an aqueous solution of an appropriate silicate, allowing the aluminate and silicate in the resultant mixture to polymerize to poly(alumino-silicate), freezing the mixture and thereafter isolating, washing, drying and recovering particulate poly(alumino-silicate) therefrom, said process characterized in that:
