Polymer Physics is a science to describe the motions of long-chain polymer molecules and their relationship with the properties of polymer materials. It has many important fundamental concepts in the polymer physics. As a result
this paper introduced the meaning and role of the important fundamental concepts relating to the chain structure
the condensation states structure
polymer solution
viscoelasticity
molecular motion and transition
and ultimate mechanical properties of the polymer by focusing on the particularity of polymer long chain to understand the equations and important fundamental theories in polymer physics.
