Abstract: A method for continuously producing a thermoplastic resin from a conjugated diene includes: primarily polymerizing a conjugated diene monomer with an aromatic vinyl monomer in a first solvent in a first reactor, and feeding a hydroxyl group-containing polymerization inhibitor and a polar hydrocarbon to the first reactor to prepare a rubber solution; and adding an aromatic vinyl monomer and a monomer copolymerizable with the aromatic vinyl monomer to the rubber solution, and subjecting the mixture to secondary polymerization in a second solvent of the same kind as the first solvent in a second reactor. The method can provide a thermoplastic resin that can have excellent color and low gloss characteristics.
