In this paper,microwave method was used to prepare diethanolamine organic montmorillonite and studied its suitable conditions,and the modified organic montmorillonite was added to dimethyl terephthalate and ethylene glycol in order for copolymerization to occur.Organic montmorillonite and copolymers were characterized by IR,XRD,etc.The results showed:the suitable diethanolamine adding amount was 18 % of dry soil mass contained in the soil slurry;suitable reaction time was 20 min;suitable reaction temperature was 60 ℃;compared with Na-montmorillonite layer spacing,modified by diethanolamine organic montmorillonite interlayer spacing increased from 1.27 nm to 1.37 nm.
