Abstract

The dynamical properties of hybrid materials obtained from mixtures of silicon alkoxides and polyethers are studied. Different techniques are used to analyze the mobility of the different parts of the material: thermal analysis (DSC, DTMA) and NMR to probe the collective motion modes and EPR to probe the local scale. The motions are dependent on the organic ratio in the blend and the covalent grafting between the two phases. Some structural models of these blends are proposed.
