Abstract

Chromanderivate (I) der allgemeinen Formel (I), in der R1 einen unsubstituierten oder substituierten C¿6?-C20-Aryl oder Aryloxyrest, eine C1-C20-Alkoxygruppe, -CN, -COOR?3¿ oder -COOH oder -CONH¿2; R?2 einen C-organischen Rest mit 8-30 C-Atomen und R3 einen Alkylrest mit 1 bis 20 C-Atomen, in welchem die Kohlenstoffkette durch Sauerstoffatome in Etherfunktion unterbrochen sein kann bedeuten. Weiterhin betrifft die Erfindung ein Verfahren zur Herstellung der erfindungsgemäßen Verbindungen (I), die Verwendung dieser Verbindungen zum Stabilisieren vor organischem Material, speziell von Kunststoffen, gegen die Einwirkung von Licht, Sauerstoff und Wärme sowie Stabilisatorgemische und Kunststoffe und andere organische Materialen, welche die erfindungsgemäßen Verbindungen (I) enthalten.
