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.
