  • Is TMQ a good antioxidant?
  • TMQ (2,2,4-trimethyl-1,2-H-dihydroquinoline) is an important antioxidant because of relatively low price and ease of application in rubber production technologies. However, due to the limited experimental data and unclear reaction mechanism, the quality of the TMQ product needs to be improved in industry processes.
  • Can polymerized TMQ reduce rubber oxidation?
  • The addition of polymerizable antioxidants is one of the most preferable methods to overcome rubber oxidation [14, 15]. One of the mostly used antioxidants is polymerized TMQ. It is a secondary amine and can strongly inhibit the oxidation reactions of rubber [16, 17, 18].
  • Which antioxidants are used in rubber vulcanization?
  • The amine and phenolic antioxidants are the most widely used rubber antioxidants (Fig. 1 b and c). Generally, the phenolic antioxidants have poor antioxidative efficiency (compared to amine antioxidants) and they can delay vulcanization, but they cause little discoloration problems.
  • 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) .
