Lectures: 1. Basic terms, history of synthetic polymers. Differences between macromolecular and low molecular weight substances, structural and repeat unit, synthesis of macromolecules, influence of the chemical structure on polymer mechanism. 2. reactions producing macromolecules. Polymerization of unsaturated compounds - radical chain polymerization, ionic chain polymerization, coordination polymerization, polyaddition, polycondensation, polymerization of cyclic compounds, examples of reactions. 3. Copolymers, reasons for their production, copolymerization parameters, relevant copolymers. 4. Chemical reactions of polymers - polymer-analogical transforms, crosslinking reactions. 5. Polymer structure (molecular structure, chemical composition, shape and size of macromolecules, molecular weight, distributional curves of molecular weight). 6. Supramolecular structure (crystalline and amorphous state), physical states of amorphous polymers and methods of their study. Structure influence on polymer properties - HDPE, LDPE, UHMWPE. 7. Rubbery state - rubber elasticity. Elastomers. 8. Non-Newtonian fluids. Polymer melt and its properties. Processing of polymer melt. 9. Degradation of polymers, depolymerisation, oxidative degradation of polymers. Polymer combustion, flame retarders and mechanism of their action. 10. Polymer bonding for nonwovens. 11. Polymer blends, polymer miscibility (thermodynamic aspect), practical application. 12. Hydrogels. Superabsorbent polymers - chemistry, production, properties, application. 13. Biodegradable polymers from renewable resources, polymer waste. 14. Special polymers. Tutorials: Tutorials will be held in two blocks because of their time demands 1. Principles of work safety in the laboratory, basic information about some dangerous chemicals (monomers, organic solvents, initiators, etc.) 2. Expandable polystyrene 3. Determination of viscosity average molar mass of polymer 4. Study of sorption kinetics of powder superabsorbents 5. Preparation of styrene by depolymerization 6. Interphase polycondensation - preparation of polyamide 7. Block polymerization of poly (methyl methacrylate) (PMMA) 8 Polymer-analogous reaction - PVA 9.

Learning outcomes
|
The aim of the course is to introduce students to the basics of macromolecular chemistry. Students will be acquainted with polymerization reactions leading to the formation of polymers, with a hierarchical structure of polymers in order to understand the principles of behavior of polymers depending on their structure. The problem is discussed in the examples, which include both conventional and special polymers, also in connection with the polymers used for the production of textile materials. Part of the lectures are dedicated to naturally occurring polymers.
Student acquire knowledges of subject.
