Amines having secondary aliphatic amino groups

摘要

The present invention relates to novel amides having secondary amino groups, a process for preparing them, adducts of these amines and their uses. The amides can be prepared in a simple way from readily available starting materials. 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 as constituent of epoxy resin compositions, in particular coatings.

主权项

1. An amine of formula (I) in which A stands for a radical of an amine after removal of a primary aliphatic amino group(s); a stands for an integer from 1 to 6 with the provision that in the case when a=1, the radical A has at least one reactive group selected from the group consisting of primary amino groups, mercapto groups, and silane groups; R1 and R2 either
independently of one another each stand for a monovalent hydrocarbon radical with 1 to 12 carbon atoms,or together they stand for a divalent hydrocarbon radical with 4 to 12 carbon atoms, which is part of an optionally substituted carbocyclic ring with 5 to 8 carbon atoms; R3 stands for a hydrogen atom or an alkyl group or an arylalkyl group or an alkoxycarbonyl group each with 1 to 12 carbon atoms; and X stands for a radical selected from the group consisting of Xa, Xb, and Xc, wherein Xa stands for —OR4 where R4 stands for a hydrogen or a hydrocarbon radical with 1 to 20 carbon atoms, optionally having at least one heteroatom, Xb stands for  wherein R5 stands for a hydrogen or a hydrocarbon radical with 1 to 20 carbon atoms, which optionally has at least one heteroatom; and Xc stands for  wherein Y stands for O or S and R6 and R7 either
together stand for a divalent radical having 2 to 10 carbon atoms, optionally having oxygen or sulfur atoms, the divalent radical being part of optionally substituted five-, six- or seven-membered ring, or
R6 stands for an alkyl, cycloalkyl, arylalkyl or acyl radical with 1 to 10 carbon atoms andR7 stands for a hydrogen or a monovalent radical with 1 to 20 carbon atoms, selected from the group consisting of an alkyl radical, cycloalkyl radical, arylalkyl radical, aryl radical, —OR8, —SR8 and —NR8R9, where R8 and R9 either each stand for a hydrocarbon radical or together stand for an alkylene radical which is part of five-, six- or seven-membered ring.
