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.
