SUPPRESSION OF ASSOCIATIVE THICKENER VISCOSITY BY PHOSPHORORGANIC COMPOUNDS Russian patent published in 2017 - IPC C08K5/521 C09D7/00 

Abstract RU 2633570 C2

FIELD: chemistry.

SUBSTANCE: associative thickener composition comprises a water dispersible polymer modified with the first hydrophobic group selected from the group consisting of hydrophobic modified ethylene oxide urethane block copolymers (EOUBC), aminated EOUBC, poly (acetal polyethers) (HM PAPE) modified with hydrophobic groups, aminoplast polyesters modified with hydrophobic groups, polyacrylates and polymethacrylates (GM PA and GM PMA) modified with hydrophobic droups, polysaccharides modified with hydrophobic droups, an organophosphorus compound comprising one or more hydrophobic groups with a low VOC content and water.

EFFECT: providing the possibility to regulate or reduce the viscosity value of concentrated aqueous solution of associative thickener with exception or significant reduction in the content of volatile organic compounds in associative thickener formulations.
