RUBBER COMPOSITION FOR A TREAD, INCLUDING AN UNSATURATED THERMOPLASTIC STYRENE COPOLYMER

摘要

The present invention relates to a rubber composition comprising a styrene-butadiene copolymer (SBR), a polybutadiene (BR), an unsaturated thermoplastic styrene (TPS) copolymer and a reinforcing filler. The invention also relates to the use of such a composition for the manufacture of a tyre tread that has improved properties in terms of wear resistance, while retaining a very good level of grip on wet ground.
