Abstract:
1. A viscoelastic composition comprising water, least one polycationic quaternary ammonium compound to control the viscoelasticity of the composition, wherein the at least one polycationic quaternary ammonium compound comprises a dissymmetric bis-quaternary compound of the following general formula: wherein R wherein R wherein R wherein at least one of R wherein A wherein the viscoelastic composition provides viscoelasticity at a temperature of at least about 80° C., and wherein the combination of the at least one polycationic quaternary ammonium compound and the at least one additive is effective to obtain a viscosity of at least about 100 cP measured at a temperature of 90° C. and at a shear rate of 100 sec
