Abstract
A stabilizer composition containing (I) a compound of the formula (I) and (II) a compound of the formula (II) wherein the radicals R1 independently of one another are C1-C18 alkyl or C3-C12 cycloalkyl; the radicals X1 independently of one another are hydrogen, C1-C18 alkyl, C3-C12 cycloalkyl or a group of the formula (III-I); the radicals X2 independently of one another are hydrogen, C1-C18 alkyl, C3-C12 cycloalkyl or a group of the formula (III-II); and Y1 is C2-C12 alkylene.
