The Importance of Energetic Interactions on the Viscoelastic Properties of Polymer Solutions
The rheological behaviour of polymer fluids can1be described on a molecular basis using the entanglement concept1. In this case it is explicitely assumed that there are mechanical entanglements (above a minimum concentration and/or molecular weight) caused by the polymer chains, which are responsible for the behaviour in the linear and non-linear viscoelastic region. It has been shown in the past that a quite great number of rheological properties can be theoretically explained on this basis.
