A wide variety of polymer nanocompositesexhibiting novel property combinations were obtained via in‐situformation of silicate nanofillers during polymerization andprocessing. Key intermediates were tailor‐made silicates which wererenderer organophilic by means of cation exchange and exfoliated uponapplying shear forces. As a function of organophilic modification,interfacial coupling, and processing conditions it was possible tocontrol nanostructure formation and to improve thermal and mechanicalproperties such as toughness/stiffness balance, heat distortiontemperature, and flame retardency. Basic structure/propertycorrelations were established for nanocomposites based upon in‐situnanofillers and polymers such as polystyrene, polyamide 12,polypropylene, polymethylmethacrylate, polyurethan, and epoxy resins.
