Title:
MODIFIED CONJUGATED DIENE-BASED POLYMER, METHOD FOR PRODUCING SAME, AND RUBBER COMPOSITION COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2021/049906
Kind Code:
A1
Abstract:
The present invention relates to a modified conjugated diene-based polymer having excellent processability as well as excellent tensile strength and viscoelasticity properties, and a rubber composition comprising same, and provides a modified conjugated diene-based polymer comprising: a first chain including a conjugated diene-based monomer derived-repeat unit; a second chain including a repeat unit derived from a compound represented by chemical formula 1; and a unit derived from an alkoxy silane-based modifier, wherein the first chain and the second chain are coupled by the modifier-derived unit.
