Abstract
The invention comprises a composition comprising a combination of carbon black and at least one surface treating agent selected from the group consisting of quinone compounds, quinoneimine compounds and quinonediimine compounds, as well as methods of obtaining the composition and the use of the composition in dispersing carbon black in a natural or synthetic polymer. The composition achieves increased dispersibility and improved mixing characteristics of the carbon black and improved processability of the carbon black containing polymer.
