Master course: Polymer Chemistry and Physics (KBT026)

The course aims to provide a fundamental understanding of the chemistry and physics of polymers and focuses on the following topics: synthesis, characterisation, structure-property relationships and the physics of solutions and the solid state.

PhD course: Polymer Characterizations


This course is mainly for PhD students who have basic knowledge about polymers. The main aim of this course is to introduce the technologies for characterization of polymers. 6 credits are recommended for this course.
