    Abstract

    Nanocomposites with and without chem. interactions with the similar morphologies were successfully synthesized by combining solid-state modification (SSM) and hybridization approach (sol-gel method). 1H NMR, 29Si solid-state NMR and FT-IR studies demonstrated that silane may graft on PP as single monomeric or polymer unit which can be incorporated in the formation of silica and this form chem. link between in-situ formed silica and PP. 29Si solid-state NMR showed that silica-cluster of Q3 and Q4 type structures are formed predominantly indicating the in-situ formed clusters are close to perfect silica. ATR FT-IR characterizations of PP macroparticles pointed that silane is grafted not only on the surface but also inside the maco-and sub-particles. Similar trend was obsd. for in-situ formed silica. The SEM confirmed these findings. Typical size (30-100nm) and near-spherical shape of in-situ formed silica particles were found by SEM on TGA roasted nanocomposites
