The entanglement is characteristic of polymer chains

resulting in particular crystal structure and motion mode of polymer

as well as high internal viscosity of polymer melt and favorable strength of polymer material. In the teaching course of polymer physics

the relevant knowledge points involved in entanglement were sorted out and integrated

and the relationship between entanglement and crystallization

rubber plateau

mechanical properties and viscosity was introduced and summarized in detail. This will help students better master the thinking logic of the polymer system and integrate the important knowledge points of polymer physics. Students strengthen their understanding and memory

and deepen the understanding of the structural characteristics

motion mode and the relationship between structure and performance of polymer.
