Abstract:
Reaction products of polyepoxides with amines followed by reaction with polyalkyleneoxide modified and/or polyester-modified and/or polyether-polyester-modified isocyanates give comblike aminic polymers, and their salts. The compounds are useful as wetting and dispersing agents for organic and inorganic pigments, and as fillers for aqueous and solvent-borne systems.
