ELECTROOPTICAL PROPERTIES OF A MESOGENIC POLYMER OF COMBINED STRUCTURE IN DILUTE-SOLUTIONS AND A NEMATIC PHASE

Optical, electrooptical, and dielectric properties of a mesogenic poly mer of combined structure were examined in dilute solutions and a nema tic phase by means of flow birefringence, equilibrium electrical biref ringence, and orientational elastic deformations in electric fields. T he effect of the length of the flexible spacers in the main chain on t he electrooptical and dielectric characteristics of solutions and a ne matic phase of the studied polymer is discussed. The results obtained are compared with those reported previously for the polymers of simila r structure.
