Key words
Objectives
This course demonstrates that a lot of mechanical, physical and chemical
properties of plastics has a structural background by wich 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 phenomenons.
Part 2: chemical modification of plastics:
Modification of structure; cross-linking and vulcanization, 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.

Assessment
Written examination with oral explanation (open questions concerning the
course and the additional notes).
However, if a student gains a score of 7 or less on 20 on one of the different courses (parts of training items), he proves that his skill for certain subcompetencies is insufficient. Consequently, one can turn from the arithmetical calculation of the final assignment of quotas of a training item and the new marks can be awarded on consensus. Of course the examiners can judge that the arithmetic regulations mentioned in the study index card can also be used for 7 or less. For each deviation a detailed motivation ought to be drawn up. In that case one should point out that the skill for this subcompetency is proven to be insufficient, if the student didn’t pass the partim that is considered to be important for certain subcompetencies.
