  • Publication number: 20200283555
    Abstract: The present technology relates to alkali-swellable emulsion polymers that are useful as rheology modifiers. More specifically the present technology relates to alkali-swellable emulsion polymers containing residues of a polyunsaturated amphiphilic macromonomer. In one aspect the disclosed polymers are useful for thickening aqueous surfactant containing compositions, while providing the compositions in which they are included excellent rheology properties, clarity, and the ability to stably suspend insoluble and particulate materials over long periods of time, as well as improved thickening efficiencies.
    Type: Application
