Abstract
A method of preparing a conjugated diene-based polymer is provided including: a step of polymerizing a first conjugated diene-based monomer in solution in a first polymerization reactor to prepare a first polymer solution including a first conjugated diene-based polymer; a step of polymerizing a second conjugated diene-based monomer in solution in a second polymerization reactor to prepare a second polymer solution including a second conjugated diene-based polymer; a step of supplying a first fluid separated from the first polymer solution to a first purification unit and purifying the first fluid; and a step of supplying a second fluid separated from the second polymer solution to a second purification unit and purifying the second fluid. An apparatus for preparing a conjugated diene-based polymer is also provided.
