Discuss how you would expect the glass transition to be affected if a large, pendent group were added to the monomer unit.
 
  What will be an ideal response?

Question 2

Explain why the properties of a polymer below the glass transition temperature are different from the same properties in the same polymer above the glass transition temperature.

Answer to Question 1

Most large pendent groups will require more thermal energy to achieve long-range chain movements. Therefore, the glass transition temperature would be expected to increase.

Answer to Question 2

Below the glass transition temperature polymers are hard. This occurs because the polymer structure is relatively fixed in space. Energy input at temperatures below the glass transition temperature can generally only result in small vibrations and rotations which do not lend movement to the polymer structure. Above the glass transition temperature much more movement
