A thermotropic polyesterimide, in which the liquid-crystalline phase is of nematic structure within a useful temperature range, consists of units of formula: <CHEM> the units being in the following ratios: a/(b + c) = 1 c/b = 0 - 50/50, and preferably c/b < 30/70 The polyesterimide of the present invention possesses self-reinforcement characteristics, or reinforcement characteristics for traditional thermoplastic materials. |
