ABSTRACT:
This invention provides a process for preparing a viscoelastic aqueous solution which contains divinylsulfone-crosslinked polygalactomannan gum that is formed in situ.
An invention thixotropic aqueous medium is characterized by excellent heat/shear stability and high tolerance to the presence of inorganic salts.
A unique property of an invention thixotropic aqueous medium is a time-dependent gradual restoration of high viscosity after cessation of high shear deformation.
