摘要
The present invention relates to amino alkoxy-modified silsesquioxanes in silicon dioxide filled rubber exhausted by low volatile organic chemicals. A vulcanizable rubber composition is presented that comprises an elastomer; a reinforcing filler selected from silica, carbon black, and mixtures thereof, a cure agent; and an amino alkoxy-modified silsesquioxane (AMS) comprising one or more compounds selected from the group consisting of an amino AMS, an amino/mercaptan co-AMS, an amino/blocked mercaptan co-AMS, mixtures thereof, and weak acid-neutralized solid and aqueous solutions thereof. Addition of such compounds to the rubber composition provides improved dynamic viscoelastic and mechanical properties of the vulcanized rubber compound and predict that tire components, especially tread stocks, will provide tires having improved snow traction, lower rolling resistance but equal wet traction, increased rebound, decreased hysteresis, and a general improvement in tire performance.
