Objectives
This course demonstrates that a lot of mechanical, physical and chemical properties of plastics has a structural background by which the behaviour of the material can be predicted, in most cases.
In a second part it is indicated that plastics remain sensitive to chemical attack, forced by man or by nature, as well in solution, in the melt, as in the solid phase, with chain breakage or chain modification as result.
Topics
Part 1:
Relation between structure en properties:
States of aggregation, chain flexibility; characterization of the different states and state transitions of amorphous and crystalline polymers; characterization of copolymers and blends; time dependent phenomenon’s.
Part 2:
Chemical modification of plastics:
Modification of structure; cross-linking and vulcanisation, reactive processing; polymer degradation, recycling.
Prerequisites
The students must have a sufficient knowledge of the different branches in chemistry as from the general materials science.
Final Objectives
General scientific competences [AWC1,AWC2]:
The student is expected to think and to reason critically, creatively, scientifically about the course material and to apply the general insights to specific scientific problems.
Specific competences [SC1, 2, 8]:
The student must be able to master general chemical knowledge and skills; he must be able to apply chemical reaction mechanisms and to perform chemical syntheses.
As a future bachelor he must be alert, on a more specific way, for the influence of products and processes on health and environment.
