Abstract: [Object]An object of the present invention is to produce a polyolefin by efficiently reusing unreacted monomers at low costs.[Solution to Problem]A polymerization apparatus 1 of the present invention includes: a liquid-phase reactor 2 in which olefin monomers are subjected to liquid-phase polymerization; a vapor-phase reactor 3 in which olefin monomers are subjected to vapor-phase polymerization; a condenser 4 that condenses unreacted olefin monomers discharged from the vapor-phase reactor 3 so as to produce a liquid containing the olefin monomers; and a liquefied monomer transfer line 11 through which the liquid containing the olefin monomers is transferred from the condenser 4 into the liquid-phase reactor 2. Thus, collected unreacted monomers can be directly subjected to the liquid-phase polymerization without additionally requiring a process such as purification steps. Therefore, the unreacted olefin monomers can be reused efficiently and economically.
