Abstract
Water-soluble polymers are disclosed which comprise hydrophobic segments, each segment containing at least one hydrophobic group or comlex hydrophobic group covalently bonded to the polymer, wherein the polymer has an amount of complex hydrophobic groups sufficient to provide for enhanced thickening of aqueous solutions containing the polymer. These polymers provide superior thickening and leveling in aqueous systems through hydrophobic associations, and aid suspension of particulate materials in non-aqueous systems.
