Answer to Problem 30.37P
The given
Explanation of Solution
The given pair of polymers is,
Figure 1
The above polymer chains have both crystalline regions and amorphous regions. The ordered crystalline regions are called crystallites. Crystallites are the sections where polymer chain is bind together by intermolecular interactions. On the contrary amorphous regions are sections where polymer chains are randomly arranged. These sections are held together by weak intermolecular interactions.
A polymer containing high crystallites area possesses high
