PROBLEM TO BE SOLVED: To provide an improved method for producing the polymer of a monomer having an ethylenic double bond, by which a time for forming the coating film of a scale-preventing agent or the like can be shortened to enhance productivity and improve an effect for preventing the adhesion of polymer scales, thereby enabling the improvement in the quality of the obtained polymer product. SOLUTION: This method for producing the polymer of a monomer having an ethylenic double bond comprises polymerizing the monomer having the ethylenic double bond in a polymerizer which has coating films for preventing the adhesion of polymer scales on the surfaces such as inner walls. The coating films are formed by coating a coating liquid containing a nitrogen-containing polymer and a tannin-based compound by the use of steam as a carrier, or by coating the first coating liquid containing a nitrogen-containing polymer and the second coating liquid containing a tannin-based compound by the use of steam as a carrier.
