Polymeric Composite Materials Based On Silicate; I-Synthesis, Characterization And Formation Mechanism


Magneso-silicate has been synthesized by precipitation technique. Polyacrylamide acrylic acid and polyacrylamide acrylonitrile impregnated with inorganic ion exchanger, magneso-silicate,have beensynthesized by subjected co-monomers to gamma radiation initiated polymerization at radiation doses 25, 65 and 90KGy. The structure features of composites were investigated by sequential x-ray fluorescence spectrometer, x-ray diffraction, differential thermal- thermogravemetric analyses andinfrared spectroscopy.Formation mechanismfor these composites were conducted and the results obtained showed thatthe polymerization process were carried out in the hydrocarbon chain by addition polymerization whereas impregnation of magneso-silicate into the polymeric composites were carried out by condensation polymerization.

Keywords: Magneso-Silicate, Co-Monomers, Gamma Radiation, Condensation Polymerization.
