Research progress on relaxation behavior and models of high molecular polymers

As a polymer material with high freq uency and wide application range, its relaxation behavior has an important effect on the accuracy of its processed products, and the result of polymer chemical synthesis will ultimately affect the relaxation behavior of the polymer. This paper summarizes the characteristics of the relaxation behavior of macromolecules, and summarizes the research progress on mechanical relaxation, model, and relaxation time. The limitations of the research on the relaxation behavior of high-molecular polymers in the emerging stage are pointed out, and the future research directions are pointed out.
