Abstract
Investigations of dielectric relaxation and thermal properties of mixtures composed of liquid crystalline side-chain polysiloxane and low molecular ma ss azo-dye have been carried out. The dyes have been chosen to solublize we ll in the polymer matrix at concentrations up to 0.08 mol fraction. The die lectric relaxation experiments have shown the presence of separate processe s attributed to reorientational motions of mesogenic side groups and dye mo lecules.
