Document Type and Number:
WIPO Patent Application WO/2021/049911
Kind Code:
A1
Abstract:
The present invention relates to a modified conjugated diene-based polymer having excellent tensile strength and viscoelastic properties while also having excellent processability, and a rubber composition comprising same. The present invention provides the modified conjugated diene-based polymer comprising: a first chain comprising a repeating unit derived from a conjugated diene-based monomer; a second chain comprising a repeating unit derived from a compound represented by formula 1 or formula 2; and a unit derived from an alkoxysilane-based modifier, wherein the first chain and the second chain are coupled by the unit derived from the modifier.
