  • 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].
  • What are TMQ polymers?
  • TMQ is chemically modified to obtain new derivatives, namely; Ester, Hydarzide, Oxadiazole and Triazole. The synthesized polymers are characterized by Fourier transforms infrared spectroscopy (FTIR) and proton-nuclear magnetic resonance (1 HNMR). The formed polymers are evaluated as antioxidants for styrene-butadiene rubber (SBR) composites.
  • 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.
  • How TMQ is added to SBR?
  • TMQ and the prepared polymers are added to SBR by a concentration of 1 phr and their antioxidant activity is compared. The rheometric characteristics and the mechanical properties including tensile strength, elongation at break, modulus at 100% elongation and hardness are studied.
