Abstract
Provided is a method for preparing a styrene-butadiene copolymer having improved silica affinity through introduction of a novel reactive emulsifier. The styrene-butadiene copolymer prepared according to the disclosed method has superior affinity for thereby and thus has superior processability and tensile properties and remarkably improved dynamic properties. Therefore, when the styrene-butadiene copolymer according to the present invention is used as a tire tread material, it can greatly improve its physical properties.
