Mesomorphic SCLCP

However, there is an enormous number of possible polymer backbones that can be used for generating SCLCPs, but only a small selection have been widely used in the synthesis and evaluation of SCLCPs. In general, poly(siloxanes) and poly(aciylates) constitute the vast majority of SCLCPs. The reported role of the spacer group is to decouple the effects of the backbone from those of the mesogenic side chains. Accordingly, the backbone should not influence the mesomorphic properties of SCLCPs. However, decoupling is... 

First to observe and classify different dielectric relaxtion processes present in scLCPs were Zentel and coworkers/ who studied unoriented samples of several different polyacrylate-based scLCPs over a wide range of temperature, covering the isotropic, mesomorphic, and solid states (Fig. 4.23). They observed up to three high-frequency relaxations (namely, the and y-processes) in the glassy state, and... 

Dielectric relaxation measurements of the mesomorphic phases of scLCPs were initially carried out on unoriented samples.
