Beta-amino acid ester-modified (aspartate) curing agents and their use in polyurea vævsklæbestoffer

摘要

The present invention relates to a compound of a formula (I) in which R1, R2, R3 are respectively independent equal or various organic radicals that have no Zerewitinoff active hydrogen, R4 are independently hydrogen, equal or different organic radicals, having no Zerewitinoff active hydrogen, or together form an unsaturated or aromatic ring, which can potentially contain heteroatoms, wherein R4 have no Zerewitinoff active hydrogen, X is a linear or branched, potentially even a substituted organic radical in the chain with heteroatom, which does not have Zerewitinoff active hydrogen, n 0n2 and m 0m2, wherein n+m=2. The invention also relates to a process for producing a compound of said formula (I) as well as a polyurea system containing such a compound.
