Abstract
Polymerization and subsequent gelation of silicic acid in water were c atalyzed by amines and polyamines. Particularly effective were poly(al lylamine), poly(lysine), and poly(arginine), which promoted spontaneou s gelation. The resultant silica gel contained a sizable portion of am ines, which altered the surface properties of silica gel.
