摘要 |
<p>A process for preparing, in one step, a diene block copolymer, of which at least one of these blocks is constituted of a polyether, the number-average molecular weight of which is approximately from 100 to 5000 g/mol, and at least one other of these blocks is constituted of a diene elastomer. The process according to the invention allows a high degree of grafting of the polyether to the polymer chains. Also disclosed is a reinforced rubber composition, especially intended for the manufacture of tires, comprising such a block copolymer which is intended to interact with the reinforcing filler. Such a rubber composition has improved hysteresis properties in the vulcanized state, while retaining satisfactory processing properties in the non-vulcanized state.</p> |
