  • Can antioxidants prevent rubber aging?
  • The addition of antioxidants to rubber is one of the most economical and effective methods for delaying rubber aging. However, antioxidant migration can cause environmental pollution. To address this issue, a new reactive antioxidant was synthesized via the chemical bonding of glycidyl methacrylate (GMA) and p -aminodiphenylamine (PPDA).
  • What is oxidative aging of rubber?
  • Thermal oxidative aging is the most frequent type of rubber degradation. To delay or prevent this process, antioxidants can be added to rubber compounds during mixing. (9) Antiaging agents react primarily with the free radicals or hydrogen peroxide generated during rubber aging.
  • 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) .
