Abstract
The invention relates to a polymer composition comprising a thermoplastic elastomer TPE and a thermoplastic polyethylene polymer PE, which thermoplastic elastomer TPE is a block thermoplastic elastomer TPE1 of formula ABA, wherein A is a thermoplastic block comprising predominantly by mole α-methylstyrene units and B is a diene elastomer block comprising more than 95% by mass of diene units relative to the mass of the diene elastomer block, or a block thermoplastic elastomer TPE2 of formula A'-B'-A', wherein A' is a thermoplastic block comprising predominantly by mole α-methylstyrene units and B' is a statistical copolymer elastomer block comprising diene units and vinylaromatic units, or alternatively a mixture of the two block thermoplastic elastomers TPE1 and TPE2, which polyethylene PE has a melting temperature, Tf, in the range of 100°C to 135°C.The invention also relates to a tire comprising such a composition in all or part of its tread.
