Title:
MODIFIED CONJUGATED DIENE-BASED POLYMER AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2017/188641
Kind Code:
A3
Abstract:
The present invention relates to a conjugated diene-based polymer containing a functional group derived from a substituted styrene-based compound and a functional group derived from an aminosilane-based compound, to a method for preparing the same, and a rubber composition containing the same. The resulting modified conjugated diene-based polymer contains, on both terminals of the main chain, a functional group derived from an aminosilane-based compound of chemical formula 1 and a functional group derived from a substituted styrene-based compound of chemical formula 2, thereby exhibiting a high modification ratio, and showing excellent affinity to a filler when applied to a rubber composition. As a result, the modified conjugated diene-based polymer can prevent the coagulation of the filler in the rubber composition and increase the dispersibility of the filler, thereby improving the processability of the rubber composition.
