ABSTRACT:
Novel polyalkylpiperidine derivatives of s-triazines of the formula ##STR1## in which X and X' are a divalent organic radical, X", X.sub.1 and X.sub.2 are a direct bond or a divalent organic radical, Y, Y', Y", Y.sub.1, Y.sub.2, Z and Z' are --O--, --S--, --NH-- or --NR.sup.3 --, R is H or CH.sub.3 and R.sup.1, R.sup.2 and R.sup.3 are a monovalent organic radical or a polyalkylpiperidine group, or the group R.sup.1 --X"--Y"-- is chlorine, and R.sup.4 is H, O, alkyl, allyl or benzyl, are valuable stabilizers for polymeric materials, in particular to protect them against photochemical degradation. The derivatives are prepared by stepwise reaction of cyanuric chloride with the corresponding YH, Y'H and Y"H compounds.
If 2 or 3 of these components are identical, the corresponding symmetrically substituted triazine compounds, which are preferred, are formed.
