Learning outcomes
|
The course focused on studying the structure of polymers and their physical characteristics. Includes familiarization with the methods, instruments and standards for determining the fundamental properties of polymeric materials, both from a theoretical as well as demonstrating a practical in the laboratory. The aim is to study the structure of polymers and their physical characteristics. In addition, familiarity with the methods, instruments and standards for determining the fundamental properties of polymeric materials.
Listener gain an overview of the physical characteristics and the structure of polymeric materials, test methods for evaluation of polymers and resins.
