“…( Figure 21 ) On the other hand polymers with spacers composed of oligo(ethylene oxide) units only (y=0) did not show mesomorphism at all. It seems that in the systems with long spacers, the spacer itself needs to be semirigid to form a material able of generating stable mesophases [ 81 ].…”

This review focuses on recent developments in the chemistry of side chain liquid crystal polymers. It concentrates on current trends in synthetic methods and novel, well defined structures, supramolecular arrangements, properties, and applications. The review covers literature published in this century, apart from some areas, such as dendritic and elastomeric systems, which have been recently reviewed.

“…The last example concerns polymeric liquid crystals: Akiyama and co-workers 43 have investigated the influence of segmented spacer on mesogenic properties of side chain liquid crystal polymers. They have synthesized some liquid crystalline polyacrylates having 4-cyanobiphenyl as a typical mesogenic group and a spacer composed from poly(oxyethylene) and poly-(methylene) segments.…”

The phase behavior of some rodlike block molecules has been reviewed with reference to the polarity of constituent segments. It was found that the ability of the mesophase formation is connected with differences in polar character between the flexible chains and rigid cores. Thus the polar poly(oxyethylene) group connected with the polar rigid core reduces mesophase stability but is advantageous when put together with some apolar building blocks. An attempt at quantitative estimation of the incompatibilities of different parts of molecules by means of Hansen solubility parameters delta and Flory interaction parameters chi has also been made. On the basis of chi parameters the Gibbs free energies of mixing of these segments were calculated. The changes of Gibbs free energy reflecting the compatibility of segments and their tendency to the phase separation and the volume fraction of mesogenic rigid core reflecting their ability to arrangement in one direction appear to be crucial in terms of type of the mesophase formation.
