Dynamics of polymer materials and related topics. Dynamical processes ranging from the very local intra-molecualar motions, the cooperative segmental relaxation associated to the glass transition upto the large scale dynamics. In the former case the main objective is to identify the molecular origin of the secondary relaxations in polymers. In the second case there is a two fold objective: i) to know to what extent the segmental dynamics of amorphous polymers share the universal properties of the structural relaxation process of the small molecule glass-forming systems; ii) to understand how the segmental dynamics of a given polymer is modified when this polymer forms a part of a multi-component system. Finally, concerning the large scale dynamics, the main interest is to know the effect of polymer architecture on these processes. The dielectric relaxation techniques are the main experimental tools used in this research. However, the basis of the research methodology consists in combining the dielectric relaxation with other complementary experimental techniques.
