Goal


This lecture aims at establishing a basis of knowledge and competence for understanding fundamental structure–property relations of polymers, such to arc further teaching contents in the fields of polymer chemistry and materials engineering.

 

 

Requirements


Basic knowledge in organic and physical chemistry as well as mathematics, as taught in bachelor-level classes of these fields.
