    摘要： The present invention relates to novel polymer compositions which are obtained by neutralizing a polymer P having at least one functional moiety of the formula (I) bound to at least one of the termini and/or to the backbone of the polymer, with an oligomeric or polymeric amine PA having at least 2 amino groups per oligomer or polymer molecule.

    摘要： The present invention relates to a dispersant composition comprising: a) at least one oligomeric acid A, which has i) at least one acidic group selected from COOH and PO3H2, and ii) at least one polyoxyalkylene-ether radical of the formula (I): R—(O-A)xO-G-, where A is an C2-C4-alkan-1,2-diyl radical; X is an integer having a number average value in the range from 2 to 20; and R is hydrocarbon radical having from 1 to 30 carbon atoms; G is a chemical bond or a carbonyl group; and b) at least one polyamine B, which is selected from the group consisting of polyvinylamines, poly-C2-C3-alkyleneimines, modified poly-C2-C3-alkyleneimines, melamine compounds, modified melamine compounds, poly-(C2-C4-alkyleneether) amines, polyetheramine polyols, and modified polyetheramine polyols. The invention also relates to aqueous pigment compositions containing a dispersant composition as defined herein, a pigment component, selected from the group consisting of pigments and mixtures of at least one pigment and at least one filler, and an aqueous diluent.

    摘要： The presently claimed invention is directed to a copolymer obtained by reacting at least one isocyanate (A) comprising at least one allophanate group and at least one active double bond with at least one isocyanate reactive component (B) to form an intermediate product (C); and reacting the intermediate product (C) with at least one active double bond reactive component (D) to obtain the copolymer which can be used as dispersant. The at least one isocyanate reactive component (B) is selected from the group consisting of monofunctional polyether amine (B1), monofunctional polyether alcohol (B2), C6-C30 monofunctional alcohol (B3) and monofunctional polyester alcohol (B4).
