Novel polyamines having secondary amino groups, and a process for producing them, adducts of these polyamines and their uses. The polyamines can be prepared in a simple way from readily available reactants. They and their adducts have, in particular, a low viscosity and are suitable as constituent of polyurethane and polyurea compositions having excellent processability and high flexibility, and also constituent of epoxy resin compositions, especially coatings. |

1. An adduct AD, obtained from the reaction of at least one polyamine of Formula (I), wherein
A represents the radical of an amine after removal of a primary aliphatic amino group(s);a represents an integer from 1 to 6, provided that if a=1, the radical A has at least one reactive group selected from the group consisting of primary amino groups, secondary amino groups, hydroxyl groups and mercapto groups;R1 and R2 represent either
independently of one another, a monovalent hydrocarbon radical having 1 to 12 C atoms,or taken together, a divalent hydrocarbon radical having 4 to 12 C atoms, which is part of an optionally substituted carbocyclic ring having 5 to 8 C atoms;R3 represents a hydrogen atom or an alkyl group or arylalkyl group or alkoxycarbonyl group having 1 to 12 C atoms each;and eitherR4 represents a monovalent aliphatic cycloaliphatic or arylaliphatic radical having 1 to 20 C atoms, which optionally contains oxygen atoms, and R5 represents a hydrogen atom or a monovalent aliphatic, cycloaliphatic or arylaliphatic radical having 1 to 20 C atoms, which optionally contains oxygen atoms, or R4 and R5 together represent a divalent aliphatic radical with 3 to 30 C atoms which is part of an optionally substituted heterocyclic ring having 5 to 8 ring atoms, wherein this ring in addition to the nitrogen atom optionally contains additional heteroatoms;with at least one compound VB that bears at least one reactive group RG, wherein the reactive group RG is selected from the group consisting of isocyanate, isothiocyanate, cyclocarbonate, epoxide, episulfide, aziridine, acrylate, methacrylate, 1-ethinylcarbonyl, 1-propinylcarbonyl, maleimide, citraconimide, vinyl, isopropenyl and allyl groups. |
