Abstract
Hydrodynamic, dynamooptic, and electrooptic properties have been investigated in dilute solutions of a the methacrylate polymer [CH 2 C(CH 3 )(COO[CH 2 ] 11 Ph[OCOPhO(CH 2 ) 5 CH 3 ] 2 )] n . Dependences of hydrodynamic properties on molecular weight varying from 5.7×10 6 to 3.0× 10 6 and excluded volume effects are discussed. Unperturbed dimensions of the macromolecule are characterized by the Kuhn segment length A= 70±10 A and by the steric factor σ= 4.2. From flow and electric birefringence measurements in a dilute solution, as well as in the liquid-crystalline phase, a shear optical coefficient and a specific Kerr constant for a polymer in solution were obtained
