Zusammenfassung:Improved siliceous pigment reinforced rubber vulcanizates are provided by incorporating into the vulcanizable rubber composition a coupling amount of silanated rubber coupling agent that is the catalytic reaction product of an organohydrosilane, such as triethoxysilane, and unsaturated synthetic rubber polymer having pendant vinyl groups, such as polybutadiene rubber and styrene-butadiene rubber.
