Investigation of the impact of modified montmorillonite on the viscosity of the solutions of polyvinyl alcohol

Comparative studies of pure polyvinyl alcohol solutions and compositions based on this alcohol were carried out. The results of research on viscometers of different types — capillary (VTL-2) and ball (Geppler viscometer). The influence of montmorillonite-polyvinylpyrrolidone mixture (MPM) on the dynamic and kinematic viscosity of polyvinyl alcohol solutions was established. It was established that the viscosity of the solution of the composition based on PVA and MPM is 1.3 times higher than the viscosity of the pure polyvinyl alcohol at a concentration of 0.01 g / ml.
