Abstract

The surfaces of particulate adsorbents are consolidated by a process in which the adsorbent is impregnated with a cationic aqueous polymer solution and then treated with an anionic aqueous dispersion of a polymer having a softening point of from 60.degree. to 150.degree. C. and the materials are dried together.
