WATER-SOLUBLE POLYMER, PRODUCTION METHOD THEREOF, AND APPLICATION THEREOF.

摘要

To provide: a water-soluble polymer having excellent adsorptivity, dispersibility, and safety as well as excellent hydrophilicity, and capable of preventing coloring sufficiently and being preferably used in a detergent additive application, for example; an application thereof; a production method of the water-soluble polymer, the production method being capable of producing such a water-soluble polymer efficiently. A water-soluble polymer produced by a polymerization of a polyether compound (A) with a monomer component containing an N-vinylpyrrolidone (B), wherein the N-vinylpyrrolidone (B) is 0.01 to 0.3 parts by weight to 1 part by weight of the polyether compound (A).
