Abstract
Si descrivono nuove dibenzo [d,g] [1,3,2] -diossarosfocine sostituite di formula I Formula I In cui R1 e R2 indipendentemente l'uno dall'altro sono C1-C18 -alchile, C5-C12 - cicloalchile, fenile oppure sostituito con C1-4- alchile oppure fenil-C1-4 - alchile, R3 indica idrogeno oppure merile, n è il numero 1 oppure 2 e A per n = 1, è C1-30 - alchile, C5-12 - cicloalchile, fenil C1-4 - alchile oppure C2-18 - alchilene oppure C2-12 - alchilene interrotto con -NR-, -S- oppure -O- in cui R è C 1-12 - alchile oppure fenile. Esse sono adatte per stabilizzare un materiale organico, in particolare polimeri sintetici, principalmente come agenti stabilizzanti della lavorazione (agenti stabilizzanti nei confronti del calore) per poliolefine.
