ABSTRACT:
A method of improving balance of properties, such as increased reinforcement and reduced rolling resistance of a rubber compound, comprising mixing the rubber compound with a carbon black and a silane coupling agent for a period of between about 10 seconds and 20 minutes at a temperature of between about 160.degree. C. and 180.degree. C. such as a styrene butadiene rubber compound, is disclosed. The method involves mixing the rubber compound "in situ" with a carbon black and Bis(3-triethoxysilylpropyl)-tetrasulfane at ambient temperature.
