Zusammenfassung: | Provided is a method for preparing a conjugated diene-based copolymer, and more specifically, a method for preparing a conjugated diene-based copolymer, a conjugated diene-based copolymer prepared therefrom, and a rubber composition including the same, the method including: (S10) performing emulsion polymerization on an α-methylstyrene monomer, a conjugated diene-based monomer, and a hydroxyalkyl(meth)acrylate monomer, wherein the α-methylstyrene monomer and the conjugated diene-based monomer are added together at one time when a polymerization conversion ratio of the emulsion polymerization is 0%, and the hydroxyalkyl(meth)acrylate monomer is divisionally added two or more times when the polymerization conversion ratio of the emulsion polymerization is 0% to 80%, the α-methylstyrene monomer is added in an amount of 10% by weight to 50% by weight, the conjugated diene-based monomer is added in an amount of 49% by weight to 89% by weight, and the hydroxyalkyl(meth)acrylate monomer is added in an amount of 0.1% by weight to 5% by weight, based on the total monomer amount. |
