Paper Abstract

Optical anisotropy induction and relaxation in azobenzene containing polymer films under polarized UV-light irradiation were investigated by UV and IR spectroscopy methods. The dependence of anisotropy relaxation on the exposure was established. The result are interpreted supposing the partial ordering of macrochains fragments in the irradiated films. The difference in dichroism and birefringence kinetics as well as IR spectra measurements support the model proposed.
