Abstract: Provided is a method of producing a stabilized polymer by which, while imparting sufficient stabilizing effect to the polymer of a monomer having an ethylenically unsaturated bond, the amount of residual solvent in the polymer can be reduced and the occurrence of foaming can be inhibited. The method of producing a stabilized polymer comprises the step of adding an antioxidant having a melting point of 70° C. or lower to a catalyst system or a polymerization system before or during polymerization of a monomer having an ethylenically unsaturated bond such that 0.005 to 0.5 parts by mass of the antioxidant is incorporated with respect to 100 parts by mass of a polymer obtained by the polymerization of the monomer having an ethylenically unsaturated bond.
