1490940 Metal complexes of sterically hindered amines CIBA-GEIGY AG 17 June 1976 [19 June 1975 2 Dec 1975 18 March 1976] 25072/76 Heading C2C [Also in Division C3] Novel compounds of the formula I wherein M is a doubly or triply positively charged metal ion; w is 2 or 3; p is 1 or 2; q is 1 or 2; r is equal to the number, to half the number or to a quarter of the number of the #N-Y groups present within the bracket q; R 1 , R 2 , R 3 and R 4 independently of one another are alkyl, or R 1 and R 3 together are alkylene, or R 1 and R 2 or R 3 and R 4 , independently of one another, together are alkylene or azaalkylene; and, if q is 1, Y is hydrogen, oxyl, optionally substituted alkyl, alkenyl, alkynyl or aralkyl; or, if q is 2, Y is alkylene, alkenylene, alkynylene or arylenedialkylene; s is a value from 0 to 2; X is a divalent organic radical which supplements the N-containing ring to form a 5-7- membered ring, or is two monovalent organic radicals; and L is a singly charged anion of an aliphatic carboxylic acid, of an aminophosphinic or aminophosphonic acid or of an enol of Formula II wherein Z is oxo or optionally substituted imino, R 5 is alkyl, alkenyl, cycloalkyl, aralkyl or aryl, R 6 is hydrogen, alkyl, alkenyl, cycloalkyl, aralkyl, aryl or alkoxycarbonyl, or R 5 and R 6 together are optionally substituted 1,4- butadi-1,3-enylene or 1,4-butylene, and R 7 is optionally substituted alkyl, alkenyl, cycloalkyl, aralkyl, aryl, alkoxy or optionally substituted amino, and novel mixtures composed of a compound of the formula and a compound of the formula are prepared by respectively reacting or mixing compounds having the above Formulµ XII and XIII. The novel compounds and mixtures may be used as stabilizers for organic polymers. |
