Abstract
The nanocomposite material formed by in situ polymn. of Me methacrylate in the periodic mesoporous silica MCM-41 was characterized by carbon and silicon CP MAS NMR spectroscopy. Cross polarization dynamics demonstrate the efficient magnetization transfer from the polymer hydrogens to the silicon atoms and the intimacy of the two nanophases. The results are implemented by (1H-29Si) 2D HETCOR expts.
