Triazine derivatives as stabilizers for organic materials
Abstract
Abstract Triazine derivatives of formula ##STR1## in which R 1 is a tertiary alkyl radical, R 2 is hydrogen or a substituent, e.g. alkyl, n is 0 or an integer, R 3 is --NH-- or --O--CH 3 -- m Wherein m is an integer, X is --O--, --S-- or --NR 6 --, wherein R 6 is hydrogen or a substituent, e.g. alkyl or phenyl, R 4 is one of the radicals signified by R 6 , or, when X is --NH--, a radical of formula ##STR2## R 1 , R 2 , n and R 3 being as indicated above, OR R 4 , R 6 and the common nitrogen atom, and optionally a further hetero atom, form a saturated 5- or 6-membered heterocyclic ring, And R 5 is one of the radicals signified by --X--R 4 , or a substituent, e.g. alkyl, Are useful for stabilizing organic materials, e.g. polypropylene, against the degradative effects of oxygen, heat and/or light.
