  • Stain resistant plasticizers and compositions
    Patent number: 4656214
    Abstract: Novel compounds are provided which have been found to be particularly useful as stain resistant plasticizers. These plasticizers impart improved low temperature flexibility to the plasticized compositions. In addition, the novel plasticizers of this invention have been found to provide plastisols and organosols of low viscosity, which is a very advantageous property for plastisols and organosols intended for use in the manufacture of vinyl sheet floorings since it enables a reduction in the amount of volatile solvent normally employed.
