Make two schematic plots of the logarithm of relaxation modulus versus temperature for an amorphous polymer (curve
Question:
Make two schematic plots of the logarithm of relaxation modulus versus temperature for an amorphous polymer (curve C in Figure).
(a) On one of these plots demonstrate how the behavior changes with increasing molecular weight.
(b) On the other plot, indicate the change in behavior with increasing cross linking.
