Process for preparing a diene copolymer comprising a polyether block, diene copolymer comprising a polyether block, reinforced rubber composition and tire |
摘要 |
A process for preparing a functionalized or unfunctionalized diene block copolymer comprising at least one polyether block of number-average molecular weight approximately from 150 to 5000 g/mol linked to at least one block constituted of a diene elastomer via at least one silicon atom. The process 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 diene 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.
