Influence of nanoparticles on polymer chains in solution.
 Bayer, Adam ; Chamradová, Ivana (referee) ; Jančář, Josef (advisor)
High surface area of used nanoparticles and their comparable size with polymer chains, are the most important characteristics of fillers in the preparation of non-Newtonian suspensions. Such structures at different concentrations have major influence on the rheological behavior of polymer solution in solvent. With increasing volume fraction of nanofiller, there is pseudoplastic or dilatant behavior present in the dissolved elastomers. Diploma thesis studies the influence of the concentration of different elastomers (SBR and SEBS copolymers) and nanofiller (hydrophobic nanosilica) in suspension, of rheological properties.

EPDM addition influence on SBR/NR mixtures ozone resistance
 Hofmann, Jan ; Figalla, Silvestr (referee) ; Petrůj, Jaroslav (advisor)
The diploma thesis deals with the EPDM addition influence on ozone resistance of NR/SBR mixtures. The theoretical part summarizes knowledge about rubber processing, additivation and effects of ozone on vulcanized rubber. The experimental part aims on preparation of rubber blends and measurement of its mechanical, physical and rheological properties in dependance on their composition.
