  The present invention's purpose is to provide: a molecular-weight controlling agent for radical polymerization which enables controlled radical polymerization of a water-soluble monomer in an aqueous medium; a method for producing a polymer of a water-soluble vinyl monomer using the same; and a water-soluble vinyl monomer polymer. The present invention provides a molecular-weight controlling agent for radical polymerization characterized in that the agent comprises, as its active ingredient, an iodine compound represented by formula (1) and in that the solubility of the active ingredient in water is 0.5 weight % or more at 20° C. In the formula, R 1 is —COOX, —CONR 4 R 5 , an aromatic group or a cyano group, X is a hydrogen atom, an aliphatic group, an alkali metal, an alkaline earth metal, an organic ammonium or an ammonium, and R 2 , R 3 , R 4 and R 5 are each independently a hydrogen atom, an aromatic group or an aliphatic group.
