The present contribution focuses on the synthesis and characterization for the first time, of nanocomposites prepared via in situ polymerization using a bentonite, originated from Algeria, modified by hexadecyltrimethylammonium chloride (OBT) and poly (ethyl methacrylate-co-acrylonitrile (PEMAN) as a matrix.These nanocomposites were qualitatively characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Proton Nuclear Magnetic Resonance Spectroscopy (1H NMR).X-Ray Diffraction (DRX) and Transmission Electron Microscopy (TEM) analysis of the elaborated materials confirmed the formation of intercalated-partially exfoliated nanocomposites.These nanocomposites showed a significant increase in their glass transition temperature compared to the pure copolymer as investigated by Differential Scanning Calorimetry (DSC) and improved thermal stability as evidenced by Thermogravimetric analysis (TGA) and kinetics of their thermal degradation.Keywords:   poly (ethyl methacrylate-co-acrylonitrile), hexadecyltrimethylammonium chloride, intercalated nanocomposite, Maghnia bentonite, morphology, thermal stability.
