Abstract:
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′).
