Summary:The present invention relates to mixtures of sterically hindered amines of the formulae (1 ) and (2) wherein at least one of the radicals Z1, Z2, Z3, Z4, Z5 and Z6 is C1-C18 alkyloxy or C5-C7 cycloalkyloxy and the remaining of the radicals Z1, Z2, Z3, Z4, Z5 and Z6 are hydrogen, hydroxy, C1-C18 alkyloxy or C5-C7 cycloalkyloxy, and at least one of the radicals Y1, Y2, Y3, Y4, Y5 and Y6 is a group of formula -CH2-CH=CH-R and the remaining of the radicals Y1, Y2, Y3, Y4, Y5 and Y6 are hydrogen or a group of formula -CH2-CH=CH-R, and the other substituents are as defined according to the present invention, methods for stabilization of an organic material, and a process for the preparation of compounds of formula (1'). La présente invention concerne des mélanges d'amines à encombrement stérique de formules (1) et (2), dans lesquelles au moins l'un des radicaux Z1, Z2, Z3, Z4, Z5 et Z6 est un alkyloxy en C1-C18 ou cycloalkyloxy en C5-C7 et le reste des radicaux Z1, Z2, Z3, Z4, Z5 et Z6 représente l'hydrogène, hydroxy, alkyloxy en C1-C18 ou cycloalkyloxy en C5-C7, et au moins l'un des radicaux Y1, Y2, Y3, Y4, Y5 et Y6 est un groupe de formule -CH2-CH=CH-R et le reste des radicaux Y1, Y2, Y3, Y4, Y5 et Y6 représente de l'hydrogène ou un groupe de formule -CH2-CH=CH-R, et les autres substituants sont tels que définis selon la présente invention, des procédés de stabilisation d'un matériau organique, et un procédé de préparation de composés de formule (1').
