摘要

A composition utilizing terminally functionalized diene polymers or diene-vinyl substituted aromatic copolymers and oxidized carbon black particulates dispersed therein has been found to provide reduced hysteresis properties and is particularly suited for use as rubber having reduced rolling resistance or hysteresis. The polymers and copolymer are preferably terminally functionalized with a compound having a nitrogen which acts as a Lewis base when bonded to the polymer. The oxidized carbon black is characterized by a relatively high acid content, with the acid sites of the carbon black interacting with the Lewis base sites on the polymer terminals to increase the carbon-polymer affinity.
