Abstract
The invention provides an amide compound as a processing aid to improve the dispersion of silica reinforcing filler in a rubber composition, while reducing or eliminating the use of expensive bifunctional silica coupling agents. The invention further provides a vulcanizable elastomeric composition and vulcanized elastomeric products, especially pneumatic tires that exhibit decreased rolling resistance, hysteresis, and improved snow, ice, and wet traction.
