Polymer structure is the basis of the performance of polymer. Polymer structure is also the starting point and basic knowledge for students to learn about polymer science. Polymer contains primary

secondary

tertiary and quaternary structures. Primary structure has the most important role in determining the structure of polymer. The diversity of secondary structure is an specific performance of polymer. Both primary and secondary structures determine the higher order structures and properties of polymer. In the lecturing of polymer physics

emphasis the fundamental role of polymer structure

use clear knowledge context of polymer structure

explain the decisive role of polymer structure on its properties supplemented with the structure of the polymer products with excellent performance which has been tested by the market. This can solid the students' understanding of the fundamental role of polymer structure. And it can achieve the purpose to explain the structure of polymer clearly.
