Beschreibung
Zusammenfassung:	Disclosed are a class of phenolic-hydrazide compounds of diverse structure which are useful as stabilizers for polyolefins. The phenolic-hydrazide compounds inhibit oxidative degradation of polyolefins which is attributable to heat and/or ultraviolet light and is promoted or accelerated by metals, e.g., copper, in contact with the polyolefin.
