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.
