Degree of crosslinking vs temperature for different polymers

Please explain to me how to sketch a graph of temperature against the degree of cross linking for the 4 types of polymers.

Use the figure below to show how the four classes of polymers are related to each other. Your figure should be properly labeled to indicate the important mechanical properties associated with each polymer and how the degree of cross linking influences any important property transition.

Please find the attached file for the full description.
