Antioxidant regenerators are substances that reduce the radicals that are formed when a primary antioxidant donates a hydrogen atom or electron to a free radical. Tocopherol, an active primary antioxidant, is regenerated when tocopheryl radical is reduced by ascorbic acid.
Antioxidants for Adhesives Adhesives and their raw materials react like other organic materials with oxygen in a process called autoxidation.

Gallic acid is a ubiquitous compound, widely distributed in the vegetal kingdom and frequently found in the human diet. In the present work, its primary antioxidant activity has been investigated using the density functional theory (DFT), and the quantum mechanics-based test for overall free radical scavenging activity (QM-ORSA) protocol.
Primary Antioxidant 1010,It can be applied in polyolefins, such as polyethylene, polypropylene, polybutene and olefin copolymers such as ethylene-vinylacetate copolymers_OKCHEM
An octanoic acid bridged with two sulfurs so that it is sometimes also called a pentanoic acid in some naming schemes. It is biosynthesized by cleavage of LINOLEIC ACID and is a coenzyme of oxoglutarate dehydrogenase (KETOGLUTARATE DEHYDROGENASE COMPLEX).
Phenolic Antioxidants perform as free radical scavengers and are known as primary AO's, providing protection during processing and during the life of the finished article. Phenolic Antioxidants are highly effective, non-discoloring stabilizers for organic substrates which are prone to oxidation, e.g. plastics, synthetic fibers, elastomers ...

Notice that the combination of primary antioxidant DDA and secondary antioxidant ZDTC had an extraordinary effect on Z and E. This is attributed to synergy between the primary and secondary antioxidants. However, as shown in Fig. 1a, the first order model does not fit the shape of the combustion exotherm with the activation energies in Table 1.
Antioxidants. Polymers will change over time when exposed to radiation, excessive heat and/or corrosive enviroments. These changes are the result of oxidative degradation caused by free radicals which form through hydrogen abstration or homolytic scission of carbon-carbon bonds when polymers are exposed to heat, oxygen, ozone, or light.

The synthesis and study of a series of 6-substituted-2,4-dimethyl-3-pyridinols having interesting antioxidant properties is reported. The general synthetic strategy leading to the compounds involved a low-temperature aryl bromide-to-alcohol conversion as the last step. 2,4-Dimethyl-3-pyridinol (1a), 2,4,6-trimethyl-3-pyridinol (1b), and 2,4-dimethyl-6-(dimethylamino)-3-pyridinol (1d) were thus ...
