A Structural Model of the Viscoelasticity of Polymers

Аннотация

A structural approach to describe the results of dynamic measurements of polymer melts is used. The possibility of approximating the loss modulus and storage modulus frequency dependences using the equations of the structural rheological model is shown for the case when the full frequency interval is divided into sections with different states of the polymer structure. The temperature dependence of the structural and rheological parameters is investigated.
