Abstract: The present invention relates to a method of preparing an ethylene/alpha-olefin/diene-based elastic copolymer having high viscosity and a high molecular weight, in which energy efficiency of the entire process is optimized. The method of preparing the elastic copolymer includes the steps of: copolymerizing an ethylene/alpha-olefin/diene-based elastic copolymer; and separating and removing the solvent and unreacted monomers from the polymer solution and recovering the elastic copolymer, by sequentially using a gas-liquid separator and a stripper in the purification of the solvent and unreacted monomers.
