CA 2346836

A compound of formula (I) wherein n is e.g. a number from 2 to 50; R5' and R5'' are e.g. a group of formula (II); G1, G2, G3 and G4 are e.g. C1-C4alkyl; R1 is e.g. hydrogen or C1-C4alkyl; R2 is e.g. methylene; R3' is e.g. hydrogen and R3'' is e.g. hydrogen or C1-C4alkyl; R4 is e.g. C2-C8alkylene; and X is e.g. -N(R7)(R8) with R7 and R8 being independently of one another hydrogen or C1-C8alkyl, is useful for stabilizing an organic material against degradation induced by light, heat or oxidation.

L'invention se rapporte à un composé représenté par la formule (I) dans laquelle n est, par exemple, un nombre compris entre 2 et 50; R¿5?' et R¿5?'' sont, par exemple, un groupe représenté par la formule (II); G¿1?, G¿2?, G¿3? et G¿4? sont, par exemple, alkyle C¿1?-C¿4?; R¿1? est, par exemple, hydrogène ou alkyle C¿1?-C¿4?; R¿2? est, par exemple, méthylène; R¿3?' est, par exemple, hydrogène et R¿3?'' est, par exemple, hydrogène ou alkyle C¿1?-C¿4?; R¿4? est, par exemple, alkylène C¿2?-C¿8?; et X est, par exemple, -N(R¿7?)(R¿8?) où R¿7? et R¿8? sont indépendamment l'un de l'autre hydrogène ou alkyle C¿1?-C¿8?. Le composé de cette invention s'avère utile pour stabiliser les matières organiques vis à vis de la dégradation occasionnée par la lumière, la chaleur ou l'oxydation.
