Copolymers containing aminoplast units and use thereof as a dispersing agent or stabilizers

摘要

A description is given of water-soluble aminoplast ether copolymers of the following structural type: wherein Z is a glycoluril central unit, B is a radical of an essentially water-insoluble polymer and R1 is a radical of a hydrophilic organic compound. The ratio R1:B is selected within a range of about 1.5 to 4:1 and the overall mass of the water-soluble aminoplast ether copolymer is from about 2000 to 50 000 g/mol such that the copolymer is soluble in water and may be used as a dispersant for e.g. pigments in polar solvents, e.g. water.
