Some Solution Properties of Poly(5, 5'bibenzimidazole 2,2'-diyl, 1, 3- phenylene)
Abstract
Some solution property measurements have been made on two samples of Poly(5, 5'bibenzimidazole, 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.
