    • To provide a high concentration solution of a vinylpyrrolidone polymer having a low K value, which can be used in various applications such as medical applications and applications where coloring is problematic. A monomer component essentially containing N-vinylpyrrolidone, hydrogen peroxide, and ammonia are sequentially added to a copper catalyst-containing aqueous solvent and polymerized at 55 to 90° C., and the ammonia is used in an amount of 0.1 to 0.37% by weight based on the N-vinylpyrrolidone. As a result, a 40 to 60% by weight solution of a vinylpyrrolidone polymer having a K value of 60 or less, wherein the solution has: an N-vinylpyrrolidone content of 10 ppm or less relative to the vinylpyrrolidone polymer; an alkanol concentration of 100 ppm or less; and an ignition residue of 0.1% by weight or less, and a 50% by weight solution of the vinylpyrrolidone polymer has a hue (APHA) according to JIS-K3331 of 280 or less.
