Effects of climatic conditions on the properties of butadiene oligomers
Baťa, David ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The bachelor thesis is conversant of monitoring dielectric material properties in AC electric field. The electrical properties of variety liquid oligobutadiens includes are studying in their practical applications. Experimentally there are verified and analyzed influences of the climatic factors especially temperature and ultraviolet radiation on the frequency dependencies of complex permittivity parts with respect to present various functional groups in oligobutadiene chains.

Analysis of degradation mechanisms oligobutadienes
Baťa, David ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This work deals with the studies of liquid oligobutadiens properties in AC electric field by dielectric relaxation spectroscopy method. The current issue in the diagnosis of oligomeric and polymeric materials during the activity of various degradation factors and options of their alleviation and suppression was studied. The existing apparatus is modified for monitoring possibilities of polymeric materials during the action of various degradation and operational factors. Effect of climatic factors are experimentally investigated, especially UV radiation and temperature on the course of the frequency dependence of complex permittivity components with respect to the different composition and length of the polymer chain.
