|Title:||APPARATUS FOR PREPARING POLYBUTADIENE|
Disclosed is an apparatus for preparing polybutadiene that can improve productivity by minimizing the plugging effect, which occurs in the process of preparing polybutadiene, and increasing a conversion rate. The apparatus for preparing polybutadiene comprises: two first polymerization reactors which are arranged in parallel to each other so as to reduce the plugging effect, wherein butadiene (reaction raw material), a polymerization catalyst, and a solvent are fed into each of the first polymerization reactors to polymerize the reaction materials; one or more second polymerization reactors which are arranged in series with the first polymerization reactors, wherein a polymerization solution containing a butadiene polymer discharged from the first polymerization reactors is fed into the second polymerization reactors to carry out a butadiene polymerization reaction; and one or more condensers for condensing gas discharged from the first polymerization reactors and the second polymerization reactors and then supplying condensates to the first polymerization reactors and/or the second polymerization reactors.
