Hindered Phenolic Antioxidants
It is well known that Phenolic Antioxidants are favored for their non discoloration properties. But in thermal oxidation conditions or in the gas produced by the combustion of fossil fuels by-products (mainly nitrogen oxides) can also form a colored product exists, it can be used for the development of new high efficiency low antioxidant naphthol.The oxygen resistance of the hindered phenolic antioxidants is also related to the stability of the free radicals generated.
Reaction type hindered phenolic antioxidant is the use of reactive groups will be hindered phenolic antioxidant molecules to the polymer backbone, therefore, has good compatibility with polymer taking resistance and not easy to migrate, volatile and environmental advantages, can keep the antioxidant effect of unsaturated isocyanate or direct addition controllable isocyanation method can produce appropriate reaction type molecular weight antioxidants. At present, reactive hindered phenolic antioxidants have gradually become a hot topic in the field of polymer polymer.The development trend of phenolic antioxidants is to increase the molecular weight of antioxidants, reduce volatility, improve antioxidant efficiency and reduce toxicity, making them more suitable for processing and using at higher temperatures. The development and production of asymmetric hindered phenolic antioxidants represent a major trend in the field of polymer antioxidants in the world today. It has broad prospects in the application of high-performance plastic products. Reactive and polymeric hindered phenolic antioxidants are also very active. Reactive hindered phenolic antioxidants are bonded to the protected polymer chains because they contain reactive groups in polymer thermal processing or polymerization. Polymeric phenolic antioxidants are obtained by homopolymerization or copolymerization by monomers with blocked phenolic units. These two kinds of new phenolic antioxidants also represent an important research direction of antioxidant.
