Document Type and Number:
WIPO Patent Application WO/2019/216645
Kind Code:
A1
Abstract:
The present invention relates to a modified conjugated diene-based polymer and a rubber composition comprising same, wherein the modified conjugated diene-based polymer according to the present invention has a narrow molecular weight distribution while having a unimodal molecular weight distribution curve by gel permeation chromatography, and includes a modified monomer-derived functional group and a modifier-derived functional group to be represented by formula 1, thereby exhibiting excellent tensile and viscoelastic properties with excellent processability.
