Title: DIENE RUBBER COMPOSITION BASED ON A 1,3-DIPOLAR COMPOUND BEARING AN IMIDAZOLE FUNCTION AND ON A BLOCKED MERCAPTOSILANE
Abstract:
The present invention relates to a rubber composition based at least on a diene elastomer, a reinforcing filler comprising a reinforcing inorganic filler, a 1,3-dipolar compound bearing an imidazole function and a blocked mercaptosilane, the blocked mercaptosilane being a blocked thiol comprising an organooxysilyl or silanol group. Such a composition has improved processing without adversely affecting the dispersion of the reinforcing inorganic filler.
