USE OF SURFACE-TREATED CARBON BLACKS IN AN ELASTOMER TO REDUCE COMPOUND HYSTERESIS AND TIRE ROLLING RESISTANCE AND IMPROVE WET TRACTION

摘要

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.
