The present invention relates to a modified polymer with a high degree of modification and superb affinity to fillers, a method for producing the modified polymer, a rubber composition comprising same, and molded products produced from the rubber composition. The modified polymer according to the present invention comprises functional groups in the main chain and on at least one terminal of the polymer, thus can exhibit a high degree of modification and can have superb affinity to fillers such as silica. Furthermore, the rubber composition according to the present invention comprises the modified polymer having superb affinity to fillers, thus machinability can be excellent and, as a result, processed goods, for example, tires, utilizing the rubber composition can exhibit superb tensile strength, abrasion resistance, and skid resistance. |
