Layered polysilicic acid-arylamide intercalation compounds were synthesized by the reaction of H-magadiite (H2Si14O29.xH2O) and H-kenyaite (H2Si20O41.xH2O) with acrylamide saturated aqueous solutions. The formation of the intercalation compounds were ascertained by X-ray powder diffraction, IR, 13C-CP MAS NMR, DTA, and chemical analysis. However, when H-magadiite was used, a part of the intercalated acrylamide molecules was oligomerized during the intercalation. A heat treatment of the layered polysilicic acid-acrylamide intercalation compounds led to a polymerization of the acrylamide in the interlayer spaces.
