Compositions stabilised with di- or trisubstituted hydroxylamines and new di- or trisubstituted hydroylamines

摘要

Compositions are described which contain plastics, polymers, resins or lubricating oils which are sensitive to oxidative, thermal and / or actinic degradation and, as a stabilizer, at least one compound of the formula I IMAGE, in which R¹ is hydrogen, C1-C36-alkyl, C5-C12 -Cycloalkyl, C2-C9-aralkyl or C7-C9-aralkyl substituted with C1-C36-alkyl, R² means C1-C36-alkyl, C5-C12-cycloalkyl, C7-C9-aralkyl or C7 substituted with C1-C36-alkyl Represents -C9-aralkyl, n is 1 to 4, X, when n = 1, has one of the meanings given for R², when n = 2, C2-C12-alkylene, C6-C10-cycloalkylene or C8-C10-alkylene-arylene-alkylene, when n = 3, C3-C6-alkane triyl or a group of the formula IMAGE and when n = 4, C4-C6-alkane tetrayl. The compounds of formula 1 with n = 2, 3 or 4 are new, provided that at least one of R¹ and R² is C7-C9-aralkyl or C7-C9-aralkyl substituted with C1-C36-alkyl when n = Is 2 and X is C2-C12-alkylene.
