description | PURPOSE: A styrene-butadiene copolymer is provided to have excellent surface frictional characteristic and to have balanced rotation resistance, abrasion resistance, and silica processability. CONSTITUTION: A styrene-butadiene copolymer includes a reaction product of a continuous solution polymerization from a styrene-based monomer and a butadiene-based monomer, has a Mooney viscosity of 48-58 ML(1+4)/100 °C after adding a process oil, has a styrene content of 34-38 wt%, and has a vinyl content of 24-28 wt%. The continuous solution polymerization uses 0.01-0.05 phm of alkyl lithium as a main catalyst and 0.005-0.25 phm of dibutyl magnesium as a cocatalyst. |
