Document Type and Number:
WIPO Patent Application WO/2021/049914
Kind Code:
A1
Abstract:
The present invention relates to a modified conjugated diene-based polymer exhibiting excellent processability and excellent tensile strength and viscoelasticity properties, and a rubber composition comprising same, the polymer comprising: a modifier-derived unit having three or more alkoxysilane groups; a non-functional chain having a silicon-carbon bond formed at one side of the modifier-derived unit and comprising a conjugated diene-based monomer-derived repeating unit; and a functional chain having a silicon-carbon bond formed at the other side of the modifier-derived unit and comprising two or more N-functional-group-containing monomer-derived units, the polymer having a rate of change in Mooney viscosity of 20% or less.
