Structural model of viscoality of polymers
Abstract
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.
