The present invention relates to a method for preparing a rubber composition which can improve physical properties of a final product. In order to achieve the purpose of the present invention, the present invention comprises a step of preparing a polymer-dispersed rubber composition in which a polymer is dispersed in a solution phase in rubber and provides a method for preparing a rubber composition, wherein the step of preparing a polymer-dispersed rubber composition comprises, after polymerization of a rubber composition containing a monomer, a solvent, and a catalyst in a rubber preparation processing step, collecting a residual monomer, and introducing a polymer to a remaining rubber solution from which the residual monomer has been collected. Application of the rubber composition thus prepared, to a tire tread composite can improve durability, grip properties, low balanced rotation resistance, thus achieving effects of excellent braking and fuel-efficient characteristics, and improving abrasive wear performance.
