Polyesters, development of liquid crystalline

It was found that melts of copolyesters containing 40-90 mole percent para oxybenzoyl segments exhibited behaviors similar to those of nematic liquid crystals. 

MECHANICAL PROPERTIES OF LIQUID CRYSTALLINE POLYMER CONTAINING 60 MOL. % p-OB 

McFarlane and coworkersL have synthesized other polymers containing other moities that are also known to lead to liquid crystallinity in non-polymeric forms. Thus, a wide variety of high molecular weight copolymers exhibiting liquid crystalline melts may be prepared. Structural shapes consisting of a high degree of molecular orientations and chain extensions may be easily fabricated from such liquid crystalline melts. 

Polymers with Liquid Crystalline Side Chains 

Extensive work has been done in a number of labora-toriesZ-lUL on the synthesis and characterization of several polymers with liquid crystalline side chains. Various of the papers in this monograph deal with various aspects of such polymers containing mesomorphic side chains. A review of the potential applications of such side chain liquid crystalline polymers therefore, will be redundant.
