rubber and in the USSR as SK rubber. In the 1930s, Germany developed the emulsion copolymerisation of butadiene-styrene (Buna S), whereas sodium polybutadiene continued as the principal general purpose synthetic rubber in the Soviet Union. The advent of World War II highlighted the importance of rubber as a raw material.

- Why do we need antioxidants for rubber composites?
- Therefore, for a real application, the antioxidants are indispensable to retard the thermal-oxidative-aging process of the rubber composites and then prolong the service life. In this review, we systematically review the recent progress of antioxidants for rubber.
- Which antioxidants protect rubber from aging?
- Among them, antioxidant 2246 has a good performance to protect rubber from aging caused by heat, oxygen, and metals. Because hydrogen in phenolic antioxidants ]. By contrast, phenolic antioxidants have less effect on rubber color, and thus are widely used in light-colored rubber products . 2.3. Heterocyclic Antioxidants ].
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- Are rubber antioxidants a rational design?
- The development of medical antioxidants also inspires the rational design of rubber antioxidants. Recently, Sun, et al. synthesized a novel antioxidant (APPT) containing aromatic amine, thiourea and allyl groups by the reaction between N-phenyl-p-phenylenediamine and allyl isothiocyanate (Fig. 3 b) .
- How does rubber antioxidant work?
- To prolong the service life of rubber composites by retarding their aging processes, rubber antioxidant initially relies on the use of a coating, such as paraffin, and coal tar, to physically isolate oxygen, but this protective layer would quickly lose the utility due to wear.
- Are rubber antioxidants harmful?
- As shown in Table 1, many commonly used rubber antioxidants are damaging to human health and the environment. For example, the antioxidant MB (2-mercaptobenzimidazole), which is widely used in the manufacture of light-colored rubber products, is harmful to aquatic organisms and has a continuous effect.
