Abstract
A rubber composition containing a rubber component, a filler and at least one organofunctional silane and/or mixture of organofunctional silanes in which individual silanes possess both free and blocked mercaptan functionality or particular mixtures of the organofunctional silanes possess both free and blocked mercaptan functionality. The organofunctional silanes and silane mixtures are useful, inter alia, as coupling agents for elastomeric compositions, e.g., rubber formulations employed in the manufacture of tires, where they exhibit a desirable balance of low scorch and good performance properties.
