| Abstract: | The locus curve of intrinsic viscosity of PEKK dissolved in concentrated sulfuric acid was measured with experimented. Using a nomographic technique, through a single reduced viscosity measurement. the intrinsic viscosity of PEKK was obtained. The results were compared with the extrapalation method and Solomon - Ciuta method. It was showed that a nomographic method would offer not only a quick and accurate intrisic viscosity but also an extended concentration applicability. |
