  • Patent number: 5646212
    Abstract: This invention relates to novel polymeric compounds, more particularly to novel block or graft copolymers which are useful in dispersing inorganic pigments, lakes and/or toners in organic medium, to methods for preparing such copolymers, and to surfactant compositions containing such polymers. The block or graft copolymers of the invention belong to the class in which one type of polymeric component is derived from an oil-soluble complex monocarboxylic acid and another component which is the residue of an alkyl glycol and/or a polyoxyalkylene compounds.
