What is Thermotropic Polyesters, 8, Comparison of Two Methods of Synthesis of Regular Liquid‐crystalline Multiblock Copolymers about?

## Abstract Two methods of synthesis of regular liquid‐crystalline (LC) multiblock copolyesters are compared. A new method for the synthesis of polyesters with increased length of mesogenic units is given. This method is based on the preparation of intermediate oxalate‐groups‐containing polymers which are hydrolyzed in the next stage. The difference consists in the structure of the initial complex monomer. The new complex monomer makes it possible to obtain LC polyesters with seven 1,4‐phenylene fragments in the mesogenic unit by a simpler route.
