- 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).
- What are the future trends of rubber antioxidants?
- The perspectives on the future trends of rubber antioxidants have been presented. Elastomers, especially diene-rubbers containing unsaturated double carbon bonds in the main chains, are vulnerable to thermal/oxygen aging, which would make the elastomers less elastic and result in earlier failure of the elastomer products.
- 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.
- 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 .
