Summary

The subject deals with polymer molecular and supramolecular structure, network formation, free volume concept, glass transition, crystallization, linear and rubber elasticity, viscoelasticity, melt flow properties, yielding and fracture, miscibility and swelling of polymers, electrical properties, transport properties. Fundamental knowledge of differential and integral calculi, combinatorics, thermodynamics and chemical structure of basic polymers are required. Exemplars and tasks for homework will be given at lectures. The exam consists of written (imposition with similar tasks) and oral part.

Syllabus

2. Molar mass distribution, its effect on polymer properties.
3. Network formation, crosslinking theory, network structure.
4. Glass transition and free volume concept.
5. Thermodynamics and kinetics of crystallization.
6. Theory of rubber elasticity, its applications.
7. Viscoelasticity, models, Boltzmann superposition principle.
8. Transitions and polymer structure. Theorem of corresponding states.
9. Polymer melt flow properties - effects of shear rate, molar mass, temperature.
10. Mechanical properties. Introduction to fracture mechanics.
11. Miscibility and solubility of polymers. Phase separation.
12. Effects of anisotropy (orientation) on polymer properties. Polymer composites.
13. Electrical conductivity. Dielectric properties.
14. Diffusion of gases in polymer membranes. Heat capacity.
