Abstract
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.
Claims10
Process for producing water-soluble organic macromolecules comprising reaction at a temperature of from about 0.degree. to 150.degree. C. a water-insoluble reaction product selected from the group consisting of
- a. a polyepoxide and a secondary amine;
- b. a polymer containing ester groups and a low volatile N-tertiary substituted alkanol amine;
- the reaction product carrying at least one mole of tertiary substituted basic nitrogen atoms in 1,000 g of macromolecular substance and having a molecular weight from about 400 to 20,000, with a substance which will split off oxygen and continuing the reaction until the macromolecular substance is water soluble.
A water-soluble organic macromolecule comprising the reaction product prepared by reacting at a temperature of from about 0.degree. to 150.degree. C. a water-insoluble macromolecular reaction product selected from the group consisting of
- a. a polyepoxide and a secondary amine;
- b. a polymer containing ester groups and a low volatile N-tertiary substituted alkanol amine;
- the reaction product carrying at least one mole of tertiary substituted basic nitrogen atoms in 1,000 g of macromolecular substance and having a molecular weight from about 400 to 20,000, with a substance which will split off oxygen, the reaction being continued until the macromolecular substance is water soluble.
