The results of rheological investigations of poly(vinyl chloride) plastisols containing constant amount of surfactant and increasing amount of water are presented. It was found that inversion phase phenomenon occurs. The next investigations determined influence addition of organic pigment and water in composition. The results show that pigment addition increases viscosity. The addition of water causes decrease of viscosity. The compositions with constant amount of water-soluble polyurethane thickener reveal another properties. The increasing amount of pigment and water causes a rise of viscosity.
Keywords: PVC plastizol, rheology, surfactants, inversion phase.
