[PDF] The effect of octylated diphenylamine and Irganox
One of the serious problems in polybutadiene rubber (PBR) production units is the color change in products, which is due to aging and the inability of antioxidants to protect the product, especially at high temperatures. In this study, the effects of amine-type antioxidant [octylated diphenylamine (OD)] and non-amine-type antioxidant (Irganox 1520) on the color
Antioxidants can be divided into two broad classes, primary and secondary, depending upon their mode of action. The most broadly used primary antioxidants are hindered phenolics. Phenolic antioxidants have traditionally been based on 2,6-di-t-butyl-4-methylphenol (BHT). This functional moiety has been incorporated into larger molecules

- What is octylated diphenylamine (c28h43n)?
- Octylated diphenylamine (C28H43N) is a medium activity, amine-type antioxidant for general-purpose elastomer use. It is antioxidant for natural rubber (NR), styrene-butadiene rubber (SBR), nitrile-butadiene rubber (NBR) and chloroprene rubber (CR).
- Is octylated diphenylamine a monophosphate antioxidant?
- Even a simple monophosphate antioxidant such as butylated hydroxytoluene (BHT) may also reduce the antioxidant activity and create a quinone system, which can act as a color agent in the polymer [ 11, 12, 13 ]. Octylated diphenylamine (C28H43N) is a medium activity, amine-type antioxidant for general-purpose elastomer use.
- How does polybutadiene destroy a polymer?
- As previously stated, the type of destruction mechanism in polybutadiene is based on the formation of cross-link between polymeric chains, and as the process of destruction goes up, cross-link increases and more energy is released into the system; however, if the antioxidant has less enthalpy, the more effective it will be.
