✦ Synopsis

Investigations of dielectric relaxation and thermal properties of mixtures composed of liquid crystalline side-chain polysiloxane and low molecular mass azo-dye have been carried out. The dyes have been chosen to solublize well in the polymer matrix at concentrations up to 0.08 mol fraction. The dielectric relaxation experiments have shown the presence of separate processes attributed to reorientational motions of mesogenic side groups and dye molecules.
