Abstract
The orientational-deformational nature of flow birefringence (FB) in s olutions of rigid-chain polymers is confirmed experimentally. The poss ibility of a direct determination of the internal viscosity parameter by the dependence of the FB relaxation time on the solvent viscosity i s demonstrated. Indirect manifestation of internal viscosity in the FB relaxation time is confirmed by the dependence of the form factor on the degree of coiling.
