Abstract
The present disclosure provides a functionalized carbon black obtained by treating an oxidized carbon black with a sulfur-containing primary or secondary amine or a salt thereof. The disclosure also relates to a process for preparing such functionalized carbon black. Furthermore, the present disclosure relates a vulcanizable rubber composition including (i) a vulcanizable rubber component, and (ii) an oxidized carbon black and (iii) a sulfur-containing primary or secondary amine or a salt thereof, or a functionalized carbon black formed from these components. The disclosure also concerns an article made from the vulcanizable rubber composition. The functionalized carbon blacks disclosed herein are particularly useful for obtaining rubber compounds with low hysteresis and enhanced abrasion resistance, e.g. for the production of energy-saving tires.
