    摘要： The invention relates to epoxide-amine adducts obtainable by reaction of one or more primary amines (A) of general formula (I) Q-NH2  (I) with one or more monoepoxides (B) of general formula (II) wherein Q is a radical Rt-[OEt]n[OPr]m[OBu]s-, in which Rt is a radical selected from alkyl radicals having 1 to 6 carbon atoms, OEt is an ethylene oxide radical, OPr is a propylene oxide radical and OBu is a butylene oxide radical, n is a number from 0 to 100, m is a number from 3 to 50 and s is a number from 0 to 20 and n+m+s=3 to 170, R is an organic radical selected from aliphatic radicals having 4 to 24 carbon atoms, aromatic radicals having 6 to 18 carbon atoms and araliphatic radicals having 7 to 34 carbon atoms, and p is 0 or 1, wherein (i) the primary amine(s) (A) and the monoepoxide(s) (B) are reacted in an equivalents ratio (A):(B) of from 1:2 to 1:1.35; and (ii) at least 40 mol % of the radicals R are selected from aromatic radicals having 6 to 18 carbon atoms and araliphatic radicals having 7 to 24 carbon atoms; and optionally subsequent salification and/or quaternization and/or modification of the reaction product. The invention furthermore relates to wetting agents and dispersants comprising or consisting of the epoxide-amine adducts and also to the production of the wetting agents and dispersants and to the use of the epoxide-amine adducts and the wetting agents and dispersants for the production of dispersions. The invention also relates to dispersions and particle formulations comprising the epoxide-amine adducts and wetting agents and dispersants.

    摘要： The invention relates to comb copolymers, which can be produced from at least one diglycidyl ether (A) of general formula (I), at least one polyether monoamine (B) of the general formula Rt—[OEt]n[OPr]m[OBu]s—NH2, at least one amine (C) of the general formula Z—R1—NH2, and optionally at least one secondary amine (D) that is free of primary amino groups and is of the general formula NHTV, wherein R stands for a residue free of epoxy groups, selected from aliphatic residues, aromatic residues, and araliphatic residues; Rt stands for a residue selected from alkyl residues having 1 to 6 carbon atoms; OEt stands for an ethylene oxide residue, OPr stands for a propylene oxide residue, and OBu stands for a butylene oxide residue; n stands for a number from 0 to 100, m stands for a number from 3 to 50, and s stands for a number from 0 to 20, and n+m+s=3 to 103; R1 stands for an aliphatic, aromatic, or araliphatic hydrocarbon residue having 1 to 12 carbon atoms; Z stands for a residue free of primary and secondary amino groups and having at least one basic nitrogen atom, T and V do not contain any secondary amino groups and stand, independently of each other, for aliphatic residues having 1 to 12 carbon atoms, aromatic residues having 6 to 12 carbon atoms, or araliphatic residues having 7 to 12 carbon atoms, wherein the molar number of the sum of the primary amino groups of the polyether monoamines (B) and primary amino groups of the amines (C) divided by the molar number of the epoxy groups of the diglycidyl ethers (A) equals a value of ⅓ to ¾. The invention further relates to the production of the comb copolymers, dispersions, particulate preparations, wetting agents, and dispersants that contain the comb copolymers, to particles coated with the comb copolymers, and to the use of the comb copolymers as wetting agents and dispersants, in particular for increasing the jetness.
