"EMULSION, EXPLOSIVE COMPOSITION IN EMULSION, EXPLOSIVE IN EMULSION, AND, PROCESS OF MANUFACTURING A COMPOSITION OF EXPLOSIVE IN EMULSION". Applicants have now found that associative thickeners can be used in emulsions for use in explosive compositions, whose associative thickeners provide rapid and reversible changes in emulsion viscosity. The associated thickeners provide explosive emulsions having the desirable characteristics of (1) significant reduction in viscosity during pumping and (2) reestablishment of relatively high viscosity when pumping is completed without damage to the components of the emulsion. It is believed that the associative thickener provides a network of physical connections through the emulsion, the network of which can be reversibly broken.
