Calcium montmorillonite from Liao-ning was organically intercalated by using cety1 trimethy1 ammonium bromide after it was treated with sodium carbonate.The optimal dosage of intercalating agent was tested.The organically intercalated montmorillonite composites were characterized by the methods of XRD,FTIR and DTA/TG.The results show that the intercalating ef-fect of the organically intercalated montmorillonite composite is the best when the amount of inter-calating agent reached 120%cation exchange capacity(CEC)
