Nonionic associative thickeners are provided having a nonionic water soluble polymer backbone containing vinyl addition polymer. The nonionic water soluble polymer backbone has at least two pendant polymeric chains attached to the nonionic water soluble polymer backbone. The pendant polymeric chains have terminal chain segments containing polyoxypropylene units. The nonionic associative thickeners are useful for modifying the rheology of compositions including aqueous compositions, such as latex containing compositions.
