Abstract
The invention relates to the high temperature mixing of elastomeric material in the presence of a quinone diimine antidegradant and carbon black, prior to vulcanization. By mixing the antidegradant quinone diimine with the elastomer prior to vulcanization, enhanced handling and processing qualities are realized in the vulcanized rubber.
