  • Patent number: 10836857
    Abstract: 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
