The present invention relates to a modified polymer having a high modification ratio and an excellent affinity with a filler, a method of preparing the same, a rubber composition including the modified polymer, and a molded article prepared from the rubber composition. The modified polymer according to the present invention may exhibit a high modification ratio by including functional groups in a polymer main chain and on at least one end thereof, and thus, an affinity with a filler, such as silica, may be excellent. Also, the rubber composition according to the present invention may have excellent processability by including the modified polymer having an excellent affinity with the filler, and, as a result, a processed product (e.g., tire) prepared by using the rubber composition may have excellent tensile strength, abrasion resistance, and wet road surface resistance.
本发明涉及一种具有高改性比和与填料具有良好亲和性的改性聚合物,其制备方法,包括改性聚合物的橡胶组合物以及由该橡胶组合物制备的成型品。本发明的改性聚合物可以通过在聚合物主链和至少一端包含功能基团来表现出高改性比,从而与二氧化硅等填料具有良好的亲和性。此外,根据本发明的橡胶组合物可以通过包含与填料具有良好亲和性的改性聚合物来具有优异的加工性能,因此,使用该橡胶组合物制备的加工产品(例如轮胎)可以具有优异的拉伸强度、耐磨性和湿路面抗滑性。
