  • Does antioxidant 4010na improve the physicomechanical properties of Biir vulcanizate?
  • The results show that the physicomechanical properties of the BIIR vulcanizate severely deteriorate when antioxidant 4010NA is used. Among the other antioxidants used, the phenolic-type antioxidant BHT is found to be better for the resin-cured BIIR vulcanizate of this study.
  • How does a rubber matrix affect antioxidative performance?
  • Obviously, the solubility/dispersity of the antioxidant within the rubber matrix is a key factor in determining the antioxidative performance, and the antioxidative efficiency of antioxidant increases with the dispersion state within the rubber matrix, owing to higher specific surface area available for termination of radicals.
  • Which vulcanizate has a better tensile strength after heat aging?
  • The vulcanizates containing antioxidants 445, RD, and BHT maintained better elongation at break than the blank after the heat aging. But only the vulcanizate containing BHT maintained a better tensile strength than the blank after the heat aging experiments at the temperature of 145°C for 48 hr.
  • 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.
