RUBBER COMPOSITION COMPRISING A POLAR THERMOPLASTIC ELASTOMER COMPRISING AN ALKYLACRYLATE BLOCK

摘要

The present invention relates to a rubber composition advantageously usable for forming the tread of a tire which comprises: (a) an elastomer matrix comprising - from 60 to 95 phr of at least one diene elastomer and - from 5 to 40 phr a thermoplastic TPE elastomer, and (b) a reinforcing filler comprising a reinforcing inorganic filler, (c) a coupling agent. The presence of the polar thermoplastic elastomer makes it possible to improve the compromise of performance wet adhesion and dry adhesion of the tread.
