  • 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 rubber antioxidants are used in China?
  • Amine antioxidants are the main rubber antioxidants produced and used in China, of which 6PPD and 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ, RD) have the highest production, accounting for more than 80% of the total amine antioxidants.
  • Does antioxidant 2246 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 can combine with the oxygen in air, their antiaging efficiency is therefore lowered compared with amine antioxidants [21, 22].
  • Can hydroxytoluene stop the autocatalytic aging reaction of rubber?
  • For instance, as shown in Fig. 1 b, butylated hydroxytoluene (BHT) could donate a hydrogen atom and convert peroxy radical to hydroperoxide, and therefore it could stop the autocatalytic aging reaction of rubber by blocking the propagation of peroxy radicals (Fig. 1 b), each BHT consumes two peroxy radicals. 3.
