Claim:
1. A process for preparing an amine adduct, in which a polyamine component (A), a polyester component (B) and a hydrocarbon component (C) are reacted in weight ratios of (A):(B)=1:1000 to 1:1 (A):(C)=1:100 to 100:1 and (B):(C)=2:1 to 50:1 in that according to reaction variant i) first a reaction intermediate (A-B) is produced from the polyamine component (A) and the polyester component (B), which is subsequently reacted with the hydrocarbon component (C) or according to reaction variant ii) first a reaction intermediate (A-C) is formed from the polyamine component (A) and the hydrocarbon component (C) and this is subsequently reacted with the polyester component (B) or according to reaction variant iii) the polyamine component (A) is reacted simultaneously with the polyester component (B) and the hydrocarbon component (C) wherein the polyamine component (A) is present in the form of at least one organic polyamine compound (A′), which in each case has at least three amino groups (A′+) selected from primary and secondary amino groups, in each case reactive with both the polyester component (B) and the hydrocarbon component (C), the polyester component (B) is present in the form of at least one polyester compound (B′), which in each case contains no primary amino groups and no secondary amino groups, in each case has at least three ester groups, and in each case contains a coupling group (B′+) present as a carboxyl group or carboxylic acid anhydride group, reactive with primary and/or secondary amino groups, and the hydrocarbon component (C) is present in the form of at least one branched or unbranched, saturated or unsaturated hydrocarbon compound (C′) each having a linking group (C′+), in each case (C′) having no primary amino groups, in each case having no secondary amino groups, in each case having no carboxyl groups and in each case having no carboxylic acid anhydride groups, and in each case (C′) having an overall ratio of carbon atoms to hetero atoms of at least 2:1, wherein the hetero atoms are selected from the group of elements consisting of at least one of O, N, P, S, and Si, wherein the linking groups (C′+) in each case have the characteristic of reacting with primary amino groups with formation of secondary amino groups and/or with secondary amino groups with formation of tertiary amino groups, and also in each case are present in the form of an epoxy function of formula (I) wherein the amine adduct is obtained in solid form at room temperature in each case and has a melting range of 30 to 200° C. and the reaction of the polyamine component (A), the polyester component (B) and the hydrocarbon component (C) takes place in that for each weight unit of polyester component (B), a maximum of 0.8 weight units of other components that do not belong to any of the components (A), (B) or (C) are optionally present.
