    摘要： The present invention relates to a rubber modifier, a conjugated diene-based polymer including a functional group derived from the modifier, and a method for preparing a modified and conjugated diene-based polymer using the modifier. The modifier is used as the modifier of a conjugated diene-based polymer and combined with a conjugated diene-based polymer chain to easily introduce a functional group having affinity with a filler. Accordingly, a modified and conjugated diene-based polymer prepared using a compound of the rubber modifier may have excellent affinity with a filler, and as a result, molded articles (for example, tires) manufactured from a rubber composition including the polymer may have excellent tensile strength, abrasion resistance, and wet traction.

    摘要： The present invention provides a modified conjugated diene-based polymer which includes a functional group derived from a substituted styrene-based compound and a functional group derived from an aminosilane-based compound, a method for preparing the same, and a rubber composition including the same. The modified conjugated diene-based polymer includes the functional group derived from an aminosilane-based compound of Formula 1 and a functional group derived from a substituted styrene-based compound of Formula 2 at both terminals of a main chain, and thus, shows a high modification ratio. When applying the polymer in a rubber composition, excellent affinity with a filler may be shown, and as a result, agglomeration of a filler in the rubber composition may be prevented, and the dispersibility of the filler may be increased, thereby improving the processability of the rubber composition.
