| abstract |
The present invention relates to a compound of the formula (I), wherein R 1 , R 2 , R 3 are independently of each other the same or different organic groups which contain no Zerewitinoff-active hydrogen, R 4 independently of each other are hydrogen, the same or different organic groups which contain no Zerewitinoff-active hydrogen, or together form an unsaturated or aromatic ring that may optionally contain heteroatoms, R 4 containing no Zerewitinoff-active hydrogen, X is a linear or branched organic group which is optionally also substituted with heteroatoms in the chain and contains no Zerewitinoff-active hydrogen, n is 0 < n < 2 and m is 0 < m < 2, with n + m = 2. The invention further relates to a method for producing the compound of the formula (I) and to a polyurea system containing such a compound. |
