| abstract |
The present invention relates to a modifying agent for modifying a polymer, a method for producing a modified conjugated diene polymer using the modifying agent, and a modified conjugated diene polymer produced thereby. In the modified conjugated diene-based polymer, a hydroxyl group and a silyl group are bonded, so the affinity with the silica-based filler is excellent. Therefore, the rubber composition comprising the modified conjugated diene-based polymer can have excellent processability, and as a result, molded articles (for example, tires) produced from the rubber composition can have excellent tensile strength, Abrasion resistance and viscoelastic properties. |
