Water-soluble organic macromolecules having a chemical structure juxtapositioned between nonionic macromolecules and macromolecules with polyelectrolyte structure are prepared by reacting water-insoluble macromolecules carrying tertiary substituted basic nitrogen atoms with a material which will release oxygen. The macromolecules, rendered water soluble through the presence of a plurality of semi-polar linkages between nitrogen and oxygen atoms, are useful as binders in water-dilutable paint systems, surface-active wetting agents, flocculating aids as, for example, in treatment of waste water, and the like. |
