Title:
MODIFIED CONJUGATED DIENE-BASED POLYMER, METHOD FOR PREPARING SAME, AND RUBBER COMPOSITION CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2017/061831
Kind Code:
A1
Abstract:
The present invention relates to a modified conjugated diene-based polymer having excellent affinity with a filler, a method for preparing the same, a rubber composition containing the same, and a tire manufactured using the rubber composition. The modified conjugated diene-based polymer may have excellent affinity with a carbon black-based filler as well as a silica-based filler since a tin-based compound-derived group is linked to one terminal and an amino silane-based compound-derived group is linked to the other terminal in the modified conjugated diene-based polymer. Thus, the rubber composition containing the modified conjugated diene-based polymer can have excellent processability, and resultantly, the processed product (e.g., a tire) manufactured using the rubber composition may have excellent tensile strength, abrasion resistance, and viscoelastic characteristics.
