The spontaneous polymerization of hydroxymethacrylate monomers by the layer aluminosilicate montmorillonite is reported. Saturation of montmorillonite by acrylic monomers gives interlayer complexes of three types, only one of which is susceptible to spontaneous polymerization. Electron‐donating sites situated within the silicate lamellae initiate the spontaneous polymerization which it is suggested proceeds by a mechanism involving radical‐anions. The results of this study together with those reported previously are used to explain the variety of effects noted when aluminosilicates are added to or heated with vinyl or acrylic monomers.
