AbstractIn literatures montmorillonite's organic modification usually use one-step intercalation method, we developed a two-step intercalation method by using two different organic salts continuously. After comparing the effects of one-step method and two-step method, we found that the effect of two-step intercalation method was much better than that of one-step method. The nanocomposites were prepared by suspension polymerization of methyl methacrylate(MMA) containing intercalated montmorillonite, and the results of their FT-IR, XRD and SEM studies proved that the montmorillonite was effectively swollen or exfoliated. Adding montmorillonite could affect the process of suspension polymerization. We found that the conversion of monomer was lowered, the shape of polymer granules was changed to be irregular, and granules' diameter was enlarged. DSC, solvency experiment and strain experiment showed that adding montmorillonite may improve the properties of PMMA because of polymer's cross-linking by montmorillonite. The best weight content of montmorillonite was about 3%.
