Flow birefringence (FB) for samples of poly-p-phenylene terephthalamide (PPPhTPhA) dissolved in sulphuric acid has been investigated; intrinsic viscosities [~/] of the solutions have been measured. Characteristic values of FB [n] and orientation angles [X/9] of the solutions were determined. Coeffic
