- Rheology (viscosity of polymer melts - Newton law, power-law; viscosity as a function of molecular weight, temperature, pressure, influence of additives and viscosity modifiers, evaluation of rheological functions, corrections of shear stress and shear rate, other rheological functions - normal stress differences, elongational viscosity, stress overshot, yield stress, flow instabilities and their elimination, modelling of flow curves - Ellis, De Kee, Carreau, Bingham, Casson). - Elasticity (deformation of solids, linear elasticity, mechanical properties). - Rubber elasticity (thermodynamics of the elastic deformation, elastic parameters and molecular structure, stress-strain curve, Mooney-Rivlin equation, statistic theory). - Viscoelasticity (Kelvin, Maxwell, Tucket model, Boltzman superposition, relaxation and retardation spectra, dynamic viscoelastic properties).
