PROBLEM TO BE SOLVED: To provide a polymerizer and a polymerization method capable of effectively preventing the polymer from adhering to vapor section inner walls or to agitator shafts. SOLUTION: This polymerizer, which is a complete mixing reactor of the vertical cylinder type with a reaction liquid therein containing at least one kind of monomer for polymerization, is provided with a reaction liquid agitation blade submerged in the reaction liquid, an auxiliary blade for agitating the reaction liquid surface layer near the reactor inner walls, and a means for cooling the monomer vapor for condensation. In the process for polymerizing the monomer out of the reaction liquid containing at least one kind of monomer in the complete mixing reactor, the reaction liquid is agitated by the submerged agitation blade, the reaction liquid surface layer near the reactor inner walls is agitated by the auxiliary blade, and the monomer vapor is cooled by the cooling means.
