An expanded series of alkoxy-and oligo(oxyethylene)-substituted thermotropic polyesters with flexible decamethylene spacers in the main chain, which have higher molecular weights than those described in an earlier report, were prepared and characterized. All of the polymers in the series are soluble in common organic solvents, and have low melting temperatures (Tm) and isotropization transition temperatures (Ti). The members of the series with oligo(oxyethylene) substituents form both smectic and nematic phases.
