| titleOfInvention | Vinylpyrrolidone polymer aqueous solution and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a simple and inexpensive method for mixing a gel-like substance into a powdery PVP obtained by heating and drying a PVP aqueous solution obtained by polymerization of a monomer such as N-vinylpyrrolidone in an aqueous medium. A means that can be suppressed is provided. When a PVP aqueous solution is obtained by polymerizing monomers such as N-vinylpyrrolidone in an aqueous medium, a singlet oxygen quencher is present in the reaction system. Alternatively, a non-volatile base is added to the PVP aqueous solution after polymerization and distilled to remove ammonia in the PVP aqueous solution. Alternatively, when storing the obtained aqueous PVP solution, a singlet oxygen quencher is present in the aqueous solution. [Selection figure] None |
