Rheological Behavior of Thermotropic Side-Chain LCPs

In this section, we summarize the study of Lee and Han (2003), who investigated the rheological behavior of a homologous series of model SCLCPs having the following chemical structure (PI-nCNCOOH)

We cannot overemphasize that the rheological behavior and the morphology of LCPs during flow are interrelated and therefore that they are inseparable, insofar as correctly interpreting rheological measurements. What is most desirable is to conduct experiments that enable one to take simultaneous measurements of the rheological 

According to Doi and Edwards (1986), the elastic stress is related to the change in the free energy per unit volume, S, for a deformation as
