MODIFIED CONJUGATED DIENE-BASED POLYMER, MODIFIED RUBBER COMPOSITION CONTAINING SAME, AND METHOD FOR PREPARING MODIFIED CONJUGATED DIENE-BASED POLYMER

摘要

The present invention relates to a method for preparing a modified conjugated diene-based polymer, a modified conjugated diene-based polymer prepared thereby, a modified conjugated diene-based polymer rubber composition containing the same, and a tire containing the same, the method comprising the steps of: (a) forming an active polymer having a reactive terminal by polymerizing a vinyl aromatic monomer and a conjugated diene-based monomer through a continuous solution polymerization method in a hydrocarbon solvent by using a multifunctional anionic polymerization initiator; (b) coupling or binding the reactive terminal of the active polymer to an aminosiloxane-based compound.
