| titleOfInvention | Polyvinyl alcohol, method for producing same and use of same |
| abstract | A polyvinyl alcohol with a saponification degree of 70 mol% or more and less than 99.9 mol%, a viscosity of an average polymerization degree of 400 or more and less than 1800, containing 0.05 mol% or more and less than 0.5 mol% aldehyde groups at the end, and 0.1 mass The absorbance at 280nm of% aqueous solution is above 0.17 and less than 0.55. By using the polyvinyl alcohol as a dispersion stabilizer for suspension polymerization of vinyl compounds, the formation of coarse particles in the obtained vinyl resin can be suppressed, particles with uniform diameters can be obtained, and the generation of fish eyes can be suppressed . In addition, by using this polyvinyl alcohol, a cross-linked product excellent in water resistance can be easily obtained. |
