Abstract

A carbon black with a ΔD50/M greater than about 0.9. The carbon black has an aggregate heterogeneity index (HI) via QTM of greater than about 2.3. The carbon black has a ΔD50 via DCP of greater than about 0.07. The QTM-HI of the present carbon black is unique for N100-200 series carbon blacks, as is the ΔD50. The carbon black is a N200 carbon black with an oil absorption number (OAN) less than about 135 and a HI of greater than about 2.3. The carbon black is also a N200 carbon black with an oil absorption number (OAN) less than about 135 and a ΔD50 of greater than about 0.07. The present invention also relates to a polymeric composition and to tires comprising a carbon black of the present invention.

Claims
