rubber antioxidants and their transformation products

Rubber Antioxidants and Their Transformation Products

Antioxidants are added to natural rubber (NR) and synthetic rubber (SR) during mastication, which is the process of transforming rubber from a strong and elastic state to a soft and plastic state [ 4, 5 ]. In addition, they could also be coated on the NR surface to achieve a similar effect [ 6 ].

Transformation Products of Tire Rubber Antioxidant 6PPD in

6PPD, a tire rubber antioxidant, poses substantial ecological risks because it can form a highly toxic quinone transformation product (TP), 6PPD-quinone (6PPDQ), during exposure to gas-phase ozone. Important data gaps exist regarding the structures, reaction mechanisms, and environmental occurrence of TPs from 6PPD ozonation. To address these data gaps, gas-phase ozonation of 6PPD was
