The course aims to explain the basic relationships and connections between the molecular and supramolecular structures of polymers and their properties. The influence of polymer structure on their thermal resistance, resistance to weathering, resistance to chemicals, solubility, electrical properties, transport phenomena, and optical properties is discussed in particular.
Students will acquire detailed information about relations between structure, chemical and physical properties of major thermo-plastic and thermosetting polymers.
