Abstract: A composition of a surface-treated-carbon-black and a functionalized polymer with functionalization along the polymer chain is disclosed, wherein the polymer represents a solution SBR including, but not limited to blends of the SBR (PBR4003) with BR, NR and EPDM, and the SBR polymer functionalization comprises polar, oxygen-containing functional groups, such that the compound exhibits reduced hysteresis and rolling resistance, improved wet traction with excellent abrasion resistance as would be used in passenger, truck and racing tires.

Abstract: A carbon black with a ?D50/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 ?D50 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 ?D50. 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 ?D50 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.

Abstract: Thermally modified carbon blacks having such properties and of such purity so as to provide improved performance properties in food contact type applications, moisture cured polymer systems, zinc-carbon “dry cell” batteries, electrochemical applications such as alkaline batteries, other electrochemical power sources and other electronic applications, and for semi-conductive wire and cable applications; bladder compounds which show both improved thermal conductivity and improved processability; and other applications which may apply but are not necessarily specified herein; the carbon blacks produced by a continuous heat treatment process, or a variation of that process as it may develop.
