- Modified styrene-butadiene copolymer with excellent dispersion property its production method and rubber composition including the same

摘要

The present invention relates to a modified styrene-butadiene copolymer, a method for manufacturing the same, and a rubber composition comprising the same. More particularly, the present invention relates to: a novel styrene-butadiene copolymer in which a terminal is modified with a hydrophilic compound to increase dispersibility of carbon black; a method for manufacturing the same; and a rubber composition comprising the same. The copolymer according to the present invention is excellent in processing ability due to the increased dispersibility of carbon black. In addition, processed products (for example, tires) manufactured by using the same have excellent tensile strength, wear resistance, and wet road resistance.
