  • 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).
  • Can rubber antioxidants contain rare-earth ions?
  • The recently reported rubber antioxidants containing rare-earth ions are summarized in Fig. 4, for instance, Sun et al. prepared a novel hindered phenol rare-earth complex (DTSm) (Fig. 4 f) by a simple and green method using 3,5-di-tert-butyl-4-hydroxybenzoic acid (DT) and samarium chloride hexahydrate (SmCl 3 ·6H 2 O) via coordination reaction.
  • Do anti-aging agents affect aging properties of composites?
  • Meanwhile, the addition of antioxidants promoted the slippage between the rubber molecular chains, which was beneficial to the processing performance of the composites. Finally, the effects of different anti-aging agents on aging properties of the composites at different time and temperatures were analyzed as well. 2. Experimental section 2.1.
  • 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.
