| Abstract |
Three different trademarks of a hindered amine stabilizer with the IUPAC name poly((6-((1,1,3,3-tetramethylbutyl)-amino)- 1, 3, 5-triazine-2, 4-diyl)(2,2,6,6-tetramethyl-4-piperidyl)imino)-1,6-hexanediyl((2, 2, 6, 6-tetramethyl-4-piperidyl)-imino)), have been analyzed and compared to each other by the use of non-aqueous packed capillary emperature-programmed liquid chromatography and light scattering detection. The analysis by this method has shown that the products contained almost 40 different homologues and other components. This is in contrast to what has been assumed earlier based on results achieved with size exclusion chromatography. The method demonstrated significant differences between the products from different manufacturers. |
