    摘要： 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 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.

    摘要： A polymer dispersant for pigments based on a graft copolymer which contains a new type of urea functional group as the pigment anchoring group. The urea groups are attached to the graft copolymer by a convenient method which involves reaction of hydroxyl functional groups built in the graft copolymer with a diisocyanate that is capped at one end with ammonia or a primary or secondary amine. The reaction is convenient and clean. Substantial crosslinking or gelling of the polymer can be easily avoided by judicious selection of appropriate ingredients and processing conditions. These materials are effective in dispersing and stabilizing a wide range of pigments in solvent based systems and are particularly useful in forming pigment dispersions that are used in a variety of solvent borne coating compositions for automobiles and trucks, where they provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.

    摘要： A polymer dispersant for pigments based on a graft copolymer wherein the graft copolymer has a weight average molecular weight of at least 3000 and has 10 to 90% by weight of a polymeric backbone and 90 to 10% by weight of macromonomer side chains attached to the backbone and wherein at least 20% by weight of the polymeric backbone has attached thereto an amide group which serves as a pigment anchoring group. The backbone may also have attached thereto an additional pigment anchoring group selected from the group consisting of aromatic ester, aromatic amine, aliphatic amine, and quaternary ammonium groups, or mixtures thereof. These materials disperse a wide variety of pigments and are useful in solvent borne coatings where they can provide improved efficiency of pigment use, lower paint viscosity, and reduced emission of volatile organic solvent.
