摘要:
Water-soluble, hydrophobically associating copolymer comprising a monoethylenically unsaturated, water-soluble, surface-active monomer (a), and a monoethylenically unsaturated, hydrophilic monomer (b) different from monomer (a). The copolymer is prepared in the presence of a nonpolymerizable surfactant and has marked thickening properties in aqueous systems.
