Abstract
The present invention relates to a process for preparing N,N'-bis(2,2,6,6-tetramethylpiperidin-4-yl)hexane-1,6-diamine. The present invention further relates to the use of N,N′-bis(2,2,6,6-tetramethylpiperidin-4-yl)hexane-1,6-diamine to prepare poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-s-triazine-2,4-diyl]-[(2,2,6,6-tetramethyl-4-piperidyl)imino]-hexamethylene-[(2,2,6,6-tetramethyl-4-piperidyl)imino], reaction material of 1,6-hexanediamine, N,N′-bis (2,2,6,6-tetramethyl-4-piperidine-yl),2,4,6-trichloro-1, 3,5-triazine,N-butyl-1-butylamine, and N-butyl-2,2,6,6-tetramethyl-4-piperidineamine, N,N′-bis(2,2,6,6-tetramethyl-4-piperidyl)-N,N′-diformylhexamethylenediamine, and 1,6-Hexanediamine, N,N′-bis(2,2,6,6-tetramethyl-4-piperidinyl)-, polymer with 2,4-dichloro-6-(4-morpholinyl)-1,3,5-triazine.
