Abstract

We have investigated the orientational order in the nematic glass formed by the side group liquid crystal polymer poly[6-(4-methoxy-4′-oxyazobenzene)hexyl methacrylate]-co-poly[methyl methacrylate] using ESR spectroscopy. In one experiment the order of the polymer backbone was investigated using a nitroxide attached to it via an ester link while in the other the nitroxide probe was dissolved in the polymer. The results of the experiments suggest that whereas the mesogenic side groups have a high orientational order the polymer backbone does not.
