Modified diene elastomer and its preparation |
摘要 |
A modified diene elastomer prepared by a process comprising the steps of polymerizing a diolefin compound containing a conjugated double bond in a liquid phase in the presence of a cobalt compound, an organic aluminum compound containing a halogen atom, and water, to give a solution containing a diene elastomer, and reacting the diene elastomer with an elastomer-modifying compound is favorably employed for the manufacture of tire tread, particularly when it is employed in combination with silica as a filler.
