Abstract
The field of side chain liquid crystalline polymers was recently reviewed.1 Therefore, this paper will discuss only recent progress made on their molecular engineering mainly by living polymerization reactions. Most of the present discussion will be made on side chain liquid crystalline polymers with mesogenic groups normally attached to the polymeric backbone.2 Figure 1 outlines the concept of side chain liquid crystalline polymers. It has been theoretically predicted3 that the conformation of the polymer backbone should get distorted in the liquid crystalline phase. Both small-angle neutron scattering (SANS) experiments4–8 and X-ray scattering experiments, 9–11 have shown that the statistical randomcoil conformation of the polymer backbone is slightly distorted in the nematic phase and highly distorted in the smectic phase.
