Structural model of viscoality of polymers


A structural approach was used to describe the results of dynamic measurements of various polymer melts. The possibility of approximation of the frequency dependences of the loss modulus and accumulation modulus using the equations of the structural rheological model is shown provided that the full frequency interval is divided into sections where there are different states of the polymer structure. The temperature dependence of the structural and rheological parameters was investigated.
Key words: structural rheological model, polymer melts, viscoelastic properties.
