The rheological properties of polyvinylidene fluoride (PVDF) solutions in N-methylpyrrolidone were studied using the rheometric method. It was shown that the viscosity of polymer solutions decreases non-linearly with increasing temperature. The viscosity of the N-methylpyrrolidone used as solvent remains practically unchanged. It was shown that solutions exhibit Newtonian behaviour at concentrations less than 7 wt.%. At higher concentrations, solutions exhibit properties of pseudoplastic fluid.
Keywords: liquids, viscosity, rheological properties, Newtonian and non-Newtonian behaviour, polyvinylidene fluoride (PVDF), N-methylpyrrolidone, materials performance, temperature dependences.
