A method, of the present disclosure, of producing a modified conjugated diene-based polymer includes a polymerization reaction process of polymerizing a conjugated diene monomer in the presence of a polymerization catalyst composition to obtain a conjugated diene-based polymer, an organic metal compound adding process of adding an organic metal compound after the polymerization reaction process, and a modification reaction process of modifying the conjugated diene-based polymer with a modifying agent after the organic metal compound adding process. A rubber composition of the present disclosure includes a modified conjugated diene-based polymer produced by the method. A tire of the present disclosure includes the rubber composition.
METHOD OF PRODUCING MODIFIED CONJUGATED DIENE-BASED POLYMER, MODIFIED CONJUGATED DIENE-BASED POLYMER, RUBBER COMPOSITION AND TIRE
