Some solution property measurements have been made on two samples of Poly5, 5bibenzimidazole, 2,2-diyl, 1-3-phenylene. Fractions were obtained from these samples by using a solvent-nonsolvent system DMAC-hexane. Intrinsic viscosities were determined for both whole samples and fractions in DMAC at 37 C. Several problems concerning sample solubility, concentration determination, and coloration of the solutions have been encountered.
