摘要

Functionalized diene elastomer, reinforced rubber composition, semi-finished rubber article, pneumatic, and cold creep reduction process of a monofunctional diene elastomer The present invention relates to a specific functionalized diene elastomer. This functionalized elastomer exhibits reduced cold creep without, however, degrading the properties of a reinforced rubber composition containing it, notably the performance properties and the hysteretic properties. This di-chain-functionalized diene elastomer has a silanol function or a polysiloxane block having a silanol end and is partially copulated or starred with tin.
