A polymer composition comprises: a) at least one block thermoplastic elastomer comprising at least one elastomer block and at least one thermoplastic block, the elastomer block(s) predominantly comprising units derived from butadiene, the thermoplastic block(s) consisting of units derived from one or more styrene monomers, b) at least one plasticizer selected from butadiene oligomers with: b1) the molar content of 1,2-polybutadiene units in said plasticizer is within a range of from 70% to 130% of that in the elastomer block of the thermoplastic elastomer, and the molar mass of the plasticizer is greater than 1500 and less than 50 000 g/mol, or else b2) the molar content of 1,2-polybutadiene units in the plasticizer is less than 70%, or greater than 130%, of that in the elastomer block of the thermoplastic elastomer, and the molar mass of the plasticizer is greater than 4000 and less than 50 000 g/mol.

The invention relates to a functionalized diene elastomer composed:

Functional diene elastomer with a low pi and improved cold flow, and rubber composition containing same

The invention relates to a functionalized diene elastomer composed a) of a specific block copolymer functionalized, at the chain end or in the middle of the chain, by a tin functional group, b) of a specific block copolymer star-branched by tin and c) of a content of less than 15% by weight, with respect to the total weight of the functionalized diene elastomer, of a specific non-tin-functional block copolymer.
