WebThe difference between Thermoplastic polymers and Thermosetting ploymers is explained on pages 11-12. Activity A2 page 35 can be used to demonstrate the difference between these two types of polymers. The effect of cross linkages between polymer chains can be illustrated by Activity A4: Making a rubber ball. Rubber is an example of an elastomer. The structure of a polymeric material can be described at different length scales, from the sub-nm length scale up to the macroscopic one. There is in fact a hierarchy of structures, in which each stage provides the foundations for the next one. The starting point for the description of the structure of a polymer is the identity of its constituent monomers. Next, the microstructure essentially de…
