      The goalFamiliarizing students with definitions rheological parameters of polymeric materials as well as with experimental methods used for their determination. Acquiring basic knowledge of empirical equations, mathematical models and molecular theories, which could describe the viscoelastic behavior of polymeric materials. Providing the opportunity to evaluate test techniques and data analysis methods for the rheological measurements.
      The outcomeStudents should be able to describe and explain the temporal relationship between forces and deformation of bodies in both solid and liquid state. Acquiring basic knowledge of dependence of rheological behavior of polymeric materials on molecular structure and their influence on polymer processing, designing plastic parts as well as their application.
      Contents
      Contents of lectures1. The definition of rheology as a science. Basic rheological parameters. Dynamic and nonperiodic experiments. Experimental techniques for rheological measurements. 2. Viscoelastici behavior of polymers. 3. Viscoelastic models. Mechanical elements and models. The distribution of relaxation and retardacion times. The molecular theory of viscoelastic behavior. 4. Effect of temperature and time on the rheological behavior of polymers. The dependence of the rheological parameters on molecular structure of polymers. 5. Polymer melts viscosity. Concentrated polymer solutions and gels. 6. Flow behavior of disperse systems. Viscosity of suspensions and emulsions. Thixotropy and rheopexy of suspension and emulsions.
      Contents of exercisesLaboratory practice - It is intended for every student to perform three experimental tests choosing from: Determination of viscosity of polymer melts by capillary viscometer. Determination of viscosity in non-periodic tests and analysis of thixotropy. Determination of rheological parameters of polymer melts and gels by dynamic mechanical analysis. Determination of physical states and phase transitions of amorphous and crystalline polymers by dynamic mechanical analysis.
