  • PMMA/MMT nanocomposites prepared by one-step in situ intercalative solution polymerization
    Huskić, Miroslav ; Žigon, Majda
    Poly(methylmetacrylate)/montmorillonite (PMMA)/(MMT) nanocomposites were prepared by one-step in situ intercalative solution polymerization involving simultaneous modification of MMT with quaternary ... ammonium salts (QAS), polymerization and polymer intercalation. Polymerization proceeded at 70 °C ina mixture of ethanol and water, whereas the nanocomposite was precipitated with only water. Four QASćs with different alkyl chain lengths, as well as a QAS with an additional acrylic group, were used to study the influence of the type of quaternary ammonium salt on intercalation. The largest extent of intercalation was achieved in nanocomposites with the QAS having one long alkyl (C16) chain. The obtained PMMA/MMT intercalated nanocomposites exhibiteda higher glass transition temperature, better thermal stability, and improved solvent resistance than the pure PMMA.
