Abstract: 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 a weak acid-neutralized solid or aqueous solution thereof, and a method of making the amino AMS, are presented. The compounds are useful in compounding, processing, cure and storage of silica-reinforced rubbers because they contain low levels of volatile organic compounds (VOC).

Abstract: A polymeric composition includes a diene elastomer; an azodicarboxy compound; and a reinforcing filler comprising silica. The composition is not foamed. A method for preparing a polymeric composition includes mixing in one or more steps: a diene elastomer; an azodicarboxy compound; and a reinforcing filler. The mixing temperature is less than 160° C. in mixing steps in which the azodicarboxy compound is present. In an embodiment, the mixing temperature is kept below the decomposition temperature of the azodicarboxy compound.
