Abstract

Electric birefringence has been investigated by using rectangular-pulse and sinusoidal-pulse fields in four low molecular weight liquids with different molecular polarities and also in solutions of cellulose carbanilate (CC) in these liquids. The parameters of equilibrium and kinetic flexibility of molecules of this polymer in various solvents were determined from the data on the dispersion of the Kerr effect in sinusoidal-pulse fields in solutions of CC. The data on equilibrium electro-optical and dynamo-optical properties of solutions of CC led to the conclusion that orientational correlation exists between the dipolar molecules of the solvent and the polar units of the polymer chain.
