"High molecular weight" is the most important characteristic of polymers compared with small molecules. It leads to various unconventional rheological phenomena such as "high viscosity" and "shear thinning". Discussions on "high viscosity" and "shear thinning" of polymer liquids were made on the causes

the guiding opinions on material production

the links with daily life and the influences of temperature and concentration. The author introduced the accumulation of contents and examples in the teaching process to deepen the understanding of the students on polymer rheology and increase the students' interest in learning.
