Preparation of ZnO/ Poly(Methylstyrene-g-Chloromethyl styrene) nanocomposite by combination of in situ and NMRP polymerization methods

first Precursor of ZnO was prepared by precipitation and ZnO nanoparticles were obtained by calcination afterwards. Surface of obtained Zinc oxide (ZnO) nanoparticles modified by silane coupling agent,3- methacryloxypropyl trimethoxy silane, to obtain good dispersity and chemical bonding in polymer matrix. Then ZnO/ Poly methylstyrene nanocomposite was prepared by in situ polymerization. The obtained polymer nanocomposite brominated and was anchored by TEMPO; Nitroxide mediated radical polymerization (NMRP) initiator, then polymerization of chloromehtyl styrene performed by NMRP procedure.The obtained samples were characterized by X-ray powder diffraction (XRD), FTIR and NMR spectroscopy.
