The critical concentration (C*) of P-8515 was 36 wt% and P-8515 exhibited characteristic nematic lyotropic liquid crystalline phases in NMP solution at different concentrations and the phase morphology changed to a typical threaded texture when shear forces were induced from PLM observations. The T-g value was 238 degrees C and the value for 5% weight loss temperature was 515 degrees C in nitrogen from DSC and TGA determinations, respectively. (c) 2007 Elsevier Ltd. All rights reserved.
