Abstract: The present invention relates to a vulcanizable rubber composition which can be used for the manufacture of tires. The invention also provides for a tire, the tread of which comprises such a composition. The rubber composition posses improved hysteresis and physical properties in the vulcanized state, while retaining satisfactory processing properties in the non-vulcanized state. The rubber composition comprises a reinforcing white filler and a diene block copolymer which is intended to interact with the white filler, the block copolymer comprising a diene block polymer having on at least one chain end thereof a polyether block having a molecular weight of between 1000 g/mol and 3000 g/mol, the polyether block corresponding to the formula: OnullCH2nullCH2nullO)nnullR,nullnull(I) in which n is an integer other than zero and R is a saturated or unsaturated hydrocarbon.

Abstract: The present invention relates to a linear or branched diene elastomer having cyclic vinyl units. A linear diene elastomer according to the invention results from at least one conjugated diene and it comprises cyclic vinyl units in a mass content of greater than or equal to 15% while having a number-average molecular weight falling within a range of from 10,000 to 300,000 g/mol. The invention also relates to a process for the production of such a linear or branched diene elastomer including cyclic vinyl units in the above-stated content and having a number-average molecular weight ranging from 10,000 to 300,000 g/mol, such that said process includes the continuous reaction of at least one conjugated diene monomer in an inert aliphatic or alicyclic hydrocarbon solvent with a catalytic system comprising an organolithium initiator, a polar agent having two or more heteroatoms and an alkali metal salt of an aliphatic or alicyclic alcohol, where: (i) the (polar agent:initiator) molar ratio is greater than or equal to 3. (ii) the (salt:initiator) molar ratio falls within a range of from 0.01 to 2, and (iii) the (salt:polar agent) molar ratio falls within a range of from 0.001 to 0.5.
