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 present invention relates to a diene rubber composition reinforced with an inorganic filler comprising a thermoplastic polymer bearing, at at least one end, a silanol or silyl ether functional group. The presence of the functional thermoplastic polymer makes it possible to improve the compromise of performances, which are the handling and the grip, of a tire having a tread that is based on such a composition.

Rubber composition including a functionalized thermoplastic polymer

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.

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

Reinforced rubber composition, exhibiting improved hysteresis, based on at least (a) an elastomeric matrix predominantly based on natural rubber, (b) a reinforcing filler and (c) a specific polyimine compound in a small proportion, preferably ranging from 1 to 5 mmol per 100 g of elastomer. This rubber composition is intended, for example, for the manufacture of a semi-finished rubber product intended for the tires of motor vehicles.

Composition made from natural rubber and a polyimine compound

The invention relates to a block diene elastomer corresponding to the following formula:
