A method of producing a vinyl-based polymer is provided in which the blocking of piping resulting from solidification of a reaction inhibitor does not occur even if the operation of supplying the reaction inhibitor is conducted at a low temperature. This method involves the polymerization of a vinyl monomer via a radical reaction, wherein a reaction inhibitor formed from a compound represented by a general formula (1), shown below, is added to the polymerization system in the form of an aqueous dispersion, either prior to commencement of the polymerization, during the polymerization, or following completion of the polymerization, depending on the effect desired.R represents an alkyl group of 3 to 6 carbon atoms.
