| titleOfInvention | Dispersion stabilizer for suspension polymerization of vinyl compound, method for producing the same, and method for producing vinyl-based polymer |
| abstract | The present invention provides a dispersion stabilizer for suspension polymerization, which exhibits high polymerization stability even when the amount of use is reduced when a vinyl compound is subjected to suspension polymerization, and a method for producing the same. The present invention relates to a dispersion stabilizer for suspension polymerization of a vinyl compound, comprising a vinyl alcohol-based polymer (A), the vinyl alcohol-based polymer (A) having a viscosity-average degree of polymerization of more than 500 and less than 1,000, and a degree of saponification of more than 65 mol % and less than 77 mol %, the modification amount based on chlorine atoms or bromine atoms is 0.10 mass % or more and less than 1.00 mass %, the cloud point of the 1 mass % aqueous solution exceeds 25.0 ° C and is less than 35.0 ° C, and the 0.1 mass % aqueous solution is based on The absorbance (x) at 280 nm of the ultraviolet absorption spectrum is more than 0.420 and less than 0.520, and the absorbance (y) of the aqueous solution at 320 nm based on the ultraviolet absorption spectrum is more than 0.300 and less than 0.400. |
