Abstract: The protonated forms of four ammonium salts(dimethyl diallyl ammonium chloride, DMDAAC; trimethylallyl ammonium chloride, TMAAC; acryloxyethyl trimethylammonium chloride, DAC; 2-methyl acryloxyethyltrimethylammonium chloride, DMC) were introduced into the interlayer region of montmorillonite template through ion-exchange reaction. X-ray diffractometry and FTIR spectra displayed that all the four monomers were intercalated into the layer region
successfully, but only two monomers undertook in situ polymerization. The different reaction activities of the four monomers were attributed to the different
space arrangement and steric hindrance of the monomers in the interlayer of montmonrillonite template.

Key words: Montmorillonite, In situ intercalation polymerization, Ammonium ion monomer
