MODIFYING AGENT, MODIFIED CONJUGATED DIENE-BASED POLYMER INCLUDING SAME AND METHOD FOR PREPARING POLYMER

Document Type and Number:

WIPO Patent Application WO/2021/060815

Kind Code:

A1

Abstract:

The present invention relates to a modifying agent that can be used in the modification of a conjugated diene polymer, and has excellent affinity with a filling agent and allows the mixing properties of a conjugated diene-based polymer to be improved, a modified conjugated diene-based polymer including a functional group derived from the modifying agent, and a method for preparing the polymer. The present invention provides a modified conjugated diene-based polymer including conjugated diene-based monomer-derived repeating units and including, at at least one terminal, a modifying agent-derived functional group represented by chemical formula 1.
