Abstract

Side-chain liquid crystalline poly(4,4'-biphenylyl methacrylate) was studied by x-ray diffraction. Three smectic phases were described using a ribbon-like structural model for the polymer chain. In the smectic S//P phase, ribbons lie flat on their sides to form layers with a spacing equal to the thickness of the ribbons. In the smectic S//A phase, the ribbons stand upright giving layers with a thickness corresponding to the length of one extended monomeric unit. In the ordered smectic S//O phase, the layer thickness also corresponds to one extended repeat unit, and the pendant groups are arranged according to a two-dimensional oblique lattice. The Schlieren texture observed in the S//P phase was analyzed in terms of symmetry.
