  • Can a rubber antioxidant enter the environment with tire-wear particles (Twps)?
  • Recently, it was reported that the rubber antioxidant N - (1,3-dimethylbutyl)- N′ -phenyl- p -phenylenediamine (6PPD or antioxidant 4020), a typical tire rubber antioxidant, could enter the surrounding environment together with tire-wear particles (TWPs) [7, 8].
  • What are the TPS of rubber antioxidants?
  • The TPs of rubber antioxidants have been observed in some studies under environmental conditions. As one of the widespread rubber antioxidants, amine antioxidants (PPDs: TMPPD, DPPD, 6PPD, and 6PPDTZ) could react with O 3 (in parts per billion volume levels) in the environment and produce PPD-quinone .
  • What is thermo-oxidative aging of rubber?
  • This review mainly focused on thermo-oxidative aging because it is the most common aging type for rubbers. The oxidative degradation of rubber proceeds by a free-radical chain reaction mechanism . As shown in Fig. 1a, rubber aging processes have three distinct phases: (i) Initiation, (ii) Propagation, and
  • 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) .
