摘要

A reduced viscosity thickener system composition comprises a cyclodextrin-containing compound having a hydrophobic cavity of a predetermined size; and a hydrophobically modified associative thickener containing terminal phobe(s) of a size capable of complexing with the hydrophobic cavity of the cyclodextrin-containing compound. A reduced viscosity thickener system composition comprises a cyclodextrin-containing compound having a hydrophobic cavity of a predetermined size; and a hydrophobically modified associative thickener containing terminal phobe(s) of a size capable of complexing with the hydrophobic cavity of the cyclodextrin-containing compound. At least a portion of the cyclodextrin-containing compound is complexed with the hydrophobically modified associative thickener such that at least a portion of the phobe(s) at least partially fills the hydrophobic cavity. Independent claims are also included for: (1) a method for providing a reduced viscosity thickener system for a polymer-containing aqueous system by: (a) providing a cyclodextrin-containing compound having a hydrophobic cavity of a predetermined size; (b) providing a hydrophobically modified associative thickener containing terminal phobe(s) of a size capable of complexing with the hydrophobic cavity of the cyclodextrin-containing compound; and (c) mixing the cyclodextrin-containing compound and the hydrophobically modified associative thickener such that at least a portion of the cyclodextrin-containing compound is complexed with the hydrophobically modified associative thickener and at least a portion of the phobe(s) at least partially fills the cavity; and (2) a method for increasing the viscosity of a polymer-containing aqueous system by mixing the reduced viscosity thickener system with a polymer-containing aqueous system, wherein the polymer is water-insoluble; and a surfactant capable of decomplexing the cyclodextrin-containing compound from the hydrophobically modified associative thickener.
