Abstract：The Organobentonites were synthesized by means of the ionexchange reaction of Na+ between tetramethylammonium chloride and tetrabutylammonium chloride quaternary ammonium salts, and sodium base bentonites. The authors used FTIR, X-ray diffraction diagram and DSC thermograms to characterize the structure of the modified bentonites, and discussed the effect of different quaternary ammonium salt on the properties of organobentonites. The results showed that ions of the surfactants had entered into the chip layer of the bentonites, changed the hydrophilic environment of the chip layer into a hydrophobic enviro nment, increased the distance among the chip layers, and improved the compatibility between montmorillonite and the organic phases. All of these have laid a base for the preparation of nanometer composite material of high polymer/bentonite.
