**Abstract**
 Polyurethane-montmorillonite nanocomposites were successfully synthesised using novel tris(2-hydroxyethyl)ammonium ions attached montmorillonite. To enhance the interfacial interactions between the polyurethane and montmorillonite, first, sodium ions present in sodium montmorillonite layers were exchanged with tris(2-hydroxyethyl)ammonium ions and resulting modified montmorillonite was used during the synthesis of polyurethane. As tris(2-hydroxyethyl)ammonium ions are bigger than the sodium ions, during the modification, the distance between montmorillonite layers increased from 1.1 nm to 1.73 nm. X-ray diffraction and transmission electron microscopy results confirm the formation of exfoliated and intercalated polyurethane-montmorillonite nanocomposites. When compared to virgin polyurethane, polyurethane-montmorillonite nanocomposites show higher thermal stability and glass transition temperature. 35 Refs.
