Abstract
Results of a study of the solution polycondensation of seven aromatic diamines with bisacid A2 are reported. The polymer of bisacid A2 with hexamethylene diamine is also synthesized. An evaluation of the polymers based upon wide angle X-ray scattering, infrared analysis, differential scanning calorimetry, thermogravimetric analysis, and mechanical properties has been carried out. Two of the polymers have been wet spun into fibers.
