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.

生物的s-三嗪式化合物的公式为## STR1 ##,其中X和X'是二价有机基团,X",X1和X2是直接键或二价有机基团,Y,Y',Y",Y1,Y2,Z和Z'为-O-,-S-,-NH-或-NR3-,R为H或
CH3,R1,R2和R3为单价有机基团或聚烷基
哌啶基团,或者R1-X"-Y"-的基团为
氯,R4为H,O,烷基,烯丙基或苄基,是用于聚合材料的有价值的稳定剂,特别是用于保护它们免受光
化学降解的影响。这些衍
生物通过
氰尿酸氯与相应的YH、Y'H和Y"H化合物的逐步反应制备。如果这些组分中有2或3个相同,则形成相应的对称取代三嗪化合物,这是首选的。
