Dynamooptical and electrooptical properties have been investigated in dilute solutions for comb-like LC polymer with mesogenic groups laterally attached by middle point to the macromolecule backbone via flexible spacer. For polymer solution in chloroform, the T-range was found where the Kerr constant K is increasing (in absolute value) with increasing T while the shear optical coefficient [n]/[eta] remains invariable. This reflects the intramolecular parking of the mesogen dipole axes with keeping the same order in mesogen optical axes. Dipole axis of the mesogenic group in the chain of this polymer is known to form a large angle with the optical one. Hence, the result can be explained by change in the mesogen short axes parking with the invariable long axes one. By other words, as evidence for present biaxiality phenomenon in molecular properties of the polymer.
