摘要： The invention relates to processes for producing an amine adduct in which in a 1st step a polyamine (A) is reacted with a monomer (C) in the form of an epoxide, an oxetane or a cyclic carbonate to afford an (intermediate) product (AC) which in a subsequent 2nd step is reacted with a monomer (B) in the form of a lactone, an acyclic hydroxycarboxylic acid or a hydroxy-functional acyclic ester to afford a (descendant) product (ACB), wherein the polyamine (A) in each case comprises at least three amino groups (A+) selected from primary and secondary amino groups and each capable of reaction with the monomers (C) and (B), the monomer (C) contains no ester groups, no carboxyl groups and no primary or secondary amino groups and in the 1st step with ring opening and formation of a hydroxyl group (H+) reacts with one of the amino groups (A+) of the polyamine (A) with additional formation of either a carbon-nitrogen bond or a urethane bond, the monomer (B) contains no primary or secondary amino groups, has a molecular weight of 90-300 g/mol and in the 2nd step reacts in such a way that any amino groups (A+) not converted in the 1st step are converted into amide groups and hydroxyl groups (H+) formed in the 1st step are converted into ester groups, wherein the monomer (B) is chosen in such a way that either in the conversion thereof a terminal hydroxyl group (H++) is additionally formed or that the monomer (B) itself already has a terminal hydroxyl group (H++) and that via the terminal hydroxyl groups (H++) with formation of (poly)ester groups a further addition of the monomer (B) is effected, wherein the process parameters are chosen such that in the 1st step and in the 2nd step altogether at least 50 mol % of the amino groups (A+) are converted.
