    摘要： Disclosed is a stabilizer composition comprising A) at least one nitrogen compound having a molecular weight of at least 150, selected from a secondary amine, wherein all substituents in the alpha position in relation to the amine-nitrogen atom are different from hydrogen, or a tertiary amine derived from a secondary amine, hydroxyl amine, alkoxyl amine or amide; and at least one iron compound. The stabilizer composition optionally contains nitroxyl radicals. Said composition is suitable for stabilizing inanimate organic material, especially styrene polyolefins or homopolymers or copolymers, against the effects of light, heat or oxygen.

    摘要： Absorbing oxygen from a closed space at a rapid rate, particularly in food packaging, is made possible by introducing an alcohol-water mixture as an activator for iron-based absorber systems, preferably including an acid to control pH. Preferred alcohols are aliphatic alcohols, particularly, monohydric alkanols, such as methanol, ethanol, n-propanol, isopropanol, sec-butanol and t-butanol. Such absorber-activator combinations are capable of rapidly reducing the oxygen in a closed package. A preferred acid is orthophosphoric acid used in an amount sufficient to establish a pH of about 0.6 to 4. A preferred iron-based absorber system employs sponge iron, optionally including a dibasic acid cooperating with the orthophosphoric acid to control pH in the system. In one preferred embodiment, the iron-based absorber is pre-activated by contacting with the activator in the substantial absence of oxygen for a predetermined period of time.
