ABSTRACT:
This invention provides a thixotropic aqueous solution that contains a thickening agent consisting of polygalactomannan gum which is crosslinked with a diglycidyl ether of polyoxyalkylene diol.
An invention thixotropic aqueous medium is characterized by excellent heat 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.
