In the course of polymer physics

several curves involving molecular motion of polymer (such as straintemperature curve

modulus-temperature curve

modulus-time curve

modulus-frequency curve

and mechanical losstemperature curve

etc.) have a great correlation. We explain these important curves in series

focusing on the clarification of their internal connection

and the emphasis of the knowledge points required for these parts of the contents. This will help students fully understand the characteristics of molecular motion and better grasp the relationship between the structure and performance of polymer. Students deepen their understanding and memory

and develop comprehensive thinking skills. This article sorts out and summarizes the relevant contents related to these important curves.
