Abstract
Official abstract text for this publication.
An intermediate of the formula (I) wherein the radicals R 1 are independently of one another methyl, ethyl or n-propyl, is suitable for preparing a compound of the formula (A) wherein X is a group of the formula (A-I) or (A-II), Y is C 11 -C 17 alkyl, and Z is a direct bond, —(CH 2 ) 8 — or —CH 2 —S—CH 2 —. The compounds of the formula (A) are useful for stabilizing an organic material against thermal, oxidative or light induced degradation.
