Abstract

See full text

Disclosed is a terminal modifier for conjugated diene polymers. The terminal modifier has both at least two amine groups and at least one alkoxysilane group. A terminally modified conjugated diene polymer which is coupled at the terminus with the terminal modifier, and a polymer composition for use in tires, comprising the terminally modified, conjugated diene polymer are also provided. When applied to tire treads, the polymer composition comprising the terminally modified, conjugated diene polymer significantly increases the disperability and binding to rubber of silica, thereby greatly contributing to an improvement of the tire treads in dynamic properties including wet traction, rolling resistance, Mooney viscosity and processability.
