Abstract
The invention relates generally to the use of processing aids to improve the dispersion of silica reinforcing filler in rubber compounds. In particular, the invention relates to the use of a monofunctional alkyl tin compound as a processing aid in the rubber compounding process. More particularly, the invention provides a vulcanizable elastomeric composition and vulcanized elastomeric products, especially pneumatic tire treadstock that exhibits decreased rolling resistance, hysteresis, and improved snow, ice, and wet traction.
