This course is an introduction to the physics and to the rheology of polymers, especially to their mechanical, thermo-mechanical, tensile and fracture properties, to their viscosity and viscoelastic behavior in both melt and solution, as well as to viscoelastic behavior of solid polymers. The aim is to provide basic theoretical knowledge necessary to estimate the most important material properties of polymers from their structure.
The course should also provide a theoretical background concerning the main methods of physical and rheological characterization of polymers and explain the prastcical importance of the studied properties for the processing and for the service life of polymeric materials.
