The thermal behavior and laser marking of a novel nematic liquid crystalline polymer is explored in this report. The glass transition and mesophase transition temperatures of this material are at 45 and 68°C, respectively, and allow the ready annealing of the nematic phase as well as conversion of the nematic to the isotropic phase by pulsed laser irradiation of metallized or dyed films of the polymer.
