ABSTRACT:
Nonionic associative thickeners are provided having a nonionic water soluble polymer backbone with at least two pendant polymeric chains attached to the nonionic water soluble polymer backbone. The pendant polymeric chains have terminal chain segments containing polyoxyalkylene units comprising 3 to 6 carbon atoms. The nonionic associative thickeners are useful for modifying the rheology of compositions including aqueous compositions, such as latex containing compositions.
