    摘要： The present invention relates to novel mono- or polynuclear melamine compounds and their use as dispersants for pigments and fillers in coating compositions, in particular in solvent-borne coating compositions. The mono- or polynuclear melamine compounds of the invention have at least one 2,4,6-triamino-1,3,5-triazine ring, wherein at least one amino groups of at least one of the 2,4,6-triamino-1,3,5-triazine rings of the mono- or polynuclear melamine compounds is of the formula A:NR1R2 (A) where R1 is H, CH(R3)OR4 or R2, R2 is CH(R3)O(A-O)x—R5, where R3 is H, C1-C10-alkyl or aryl; R4 is H, C1-C4-alkyl or C1-C4-alkoxy-C1-C4-alkyl; R5 is a hydrocarbon radical having from 1 to 40 carbon atoms; x is an integer from 2 to 500, having on average a value in the range from 2.5 to 400; A is an C2-C4-alkan-1,2-diyl radical.

    摘要： The present invention relates to novel block copolymers of general formula (I). The invention further relates to a method for producing such block copolymers and to the use of such block copolymers, particularly as additives in liquid coating-agent compositions. A{X—[O—C(O)NH—Y—NH—C(O)—O-M-B]k}n (I). In formula (I), the variables have the following meanings: n is a number in the range from 1 to 40 or 2 to 40, particularly 1 to 10 or 2 to 10 and especially 2 to 5; k is 1 or 2; A is a poly(dimethylsiloxane) block; B is a polymer block constructed of ethylenically unsaturated monomers, which optionally comprises a terminal group different from hydrogen; X is a bivalent or trivalent group having 2 to 20 C atoms, which is saturated or unsaturated and which optionally bears 1, 2, 3, or 4 substituents selected from among OH, COOH, CONH2, C1-C4 alkoxy, C1-C4 alkoxycarbonyl, and halogen; Y is a bivalent hydrocarbon group having 2 to 20 C atoms, which is saturated or unsaturated, and M is a chemical bond or C2-C10 alkylene, which can be interrupted by one or two groups not directly adjacent, selected from among O, C(═O)O, and (C═O)NH and which optionally bears 1, 2, 3, or 4 substituents selected from among OH, COOH, CONH2, C1-C4 alkoxy, C1-C4 alkoxycarbonyl, and phenyl.
