2,6-Diarylpiperidin-1-yl substituted 2-butene stabilizers.

摘要

2,6-Diarylpiperidin-1-yl substituted 2-butene stabilizers of the formula I or II T-CH2-CH=CH-CH2-T (I) T-CH2-CH=CH-CH2-N(E1)(E2) (II) where T is a 2,6-diarylpiperidin-1-yl moiety and E1 and E2 are independently alkyl, cycloalkyl, aralkyl or aryl, are effective in stabilizing organic materials against the deleterious effects of oxygen, heat and actinic radiation.
