Notes:
Thermotropic liquid-crystalline polyesters with either 4,4″-p-terphenylylene or p-phenylene-oxyterephthaloyloxy-p-phenylene as mesogenic units and dimethylsiloxane spacers in the main chain were synthesized. The thermal behaviour was studied by means of differential scanning calorimetry, polarizing microscopy, and X-ray diffractometry. The polymers show mainly smectic mesomorphism. The transition temperatures were found to be much lower than in the corresponding polyesters containing polymethylene or poly(oxyethylene) spacers.
