4.2 Mechanical properties of polymers
For polymers the variation of the tensile modulus with temperature is of
considerable significance in that, for instance, it determines whether the
plastic spoon which is stiff at room temperature remains stiff when it is used to
stir hot coffee.

Figure 4.17 Variation of tensile modulus with temperature for an amorphous
polymer
The overall way in which the tensile modulus of amorphous polymers
changes with time is the same for all such polymers, the differences between
polymers being just the actual temperatures at which the changes occur.
Figure 4.17 shows the genera ...
