Abstract
Exfoliated poly (Chloromethyl styrene-co-styrene)-g-polyacrylonitryle/organo- modified montmorillonite
[P(CMSt-co-St)-g-PAN/O-MMT] nanocomposite was synthesized through solution intercalation method by
using atom transfer and nitroxide mediated radical polymerization. At first, poly (chloromethyl styrene-costyrene) copolymer was synthesized by nitroxide - mediated “living” free radical polymerization (NMRP).
This chlorinated copolymer used as a macro initiators for atom transfer radical polymerization (ATRP). These
macro initiators were polymerized acrylonitryle monomers in the presence of CuCl as a catalyst and the 2, 2’
– bi pyridine (bpy) as a legend in the tetrahydrofurane (THF) solvent at 90oC. Organophilic montmorillonite
(O-MMT) was obtained after treating by hexadecyl trimethyl ammonium chloride salt by ion-exchange process. Finally, (PCMSt-co-PSt)-g-PMMA / O-MMT nanocomposite was prepared by solution intercalation method. The exfoliating structure of nanocomposite was probed by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
