Abstract: The present invention is a process for producing a linear block copolymer, useful as a dispersant for pigment, wherein the block copolymer comprises acetoacetyl amine functional groups which serve as pigment anchoring groups. The acetoacetyl amine functional groups can be formed by reacting hydroxyl functional groups with an acetoacetate agent and then reacting the resulted acetoacetate functional groups with a primary amine. The linear block copolymer can be an AB, ABC, or ABA block copolymer. The linear block copolymer produced by the present invention can be useful in dispersing and stabilizing a wide range of pigments in solvent based systems, and are particularly useful in providing pigment dispersions that are used in coating compositions for automobiles and trucks, where they provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.
