Abstract
A new water-soluble rigid-rod sulfonated polynaphthoyleneimide (PNIS) was synthesized. The structure of PNIS has been confirmed by elemental analysis, NMR (H-1, C-13), full X-ray investigation of model compound . Viscosity measurements, sedimentation and light-scattering experimen ts of PNIS solutions confirm the suggested aggregation of this polymer and an increase of its molecular weight without being substantially c hanged in different types of aqueous solution. These aggregates could consist of very tightly packed rigid rods.
