Title:
MODIFIED CONJUGATED DIENE-BASED POLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/130738
Kind Code:
A1
Abstract:
The present invention provides a modified conjugated diene-based polymer represented by chemical formula 1 and having a modified terminus of a polymer chain, and a preparation method therefor, the modified conjugated diene-based polymer containing a modifier-derived group having a characteristic structure, thereby enabling a beta value affecting cold flowability to be lowered by adjusting the degree of branching, and thus enabling the cold flowability of the polymer to be efficiently controlled and the Mooney viscosity increase rate thereof to be improved.
