| Abstract: | Montmorillonite was modified with long chain quaternary ammonium salt through cation exchanging reaction. The modified montmorillonite became more organophilic compared with its precursor and could be dispersed in styrene uniformly because of the effect of solvation. Polystyrene (PS)/ montmorillonite intercalated hybrid was prepared with bulk polymerization process, and then, was characterized by means of XRD, DSC, TEM and FTIR. It was found that the PS in the form of double - molecule layer intercalated the montmorillonite. The glass transition behavior of the PS was changed greatly because of the constriction of the montmorillonite layer. |
