摘要：
Three tin-containing nitroazopolymers with a tin-organic unit were synthesized and characterized by DSC, polarization microscopy, AFM and dielectric measurements, Dielectric measurements prove the existence of three relaxation ranges. No Vogel-Fulcher behaviour of the relaxation times were found. At low temperatures only different solid phases and no liquid crystalline exist.
