| titleOfInvention | Polyvinyl alcohol composition and use thereof, and method for producing vinyl resin |
| abstract | A composition (D) containing modified polyvinyl alcohol (A) and unsaturated monocarboxylic acid or its salt (B), characterized in that the average polymerization degree of modified polyvinyl alcohol (A) viscosity is 100 or more and 600 Hereinafter, the degree of saponification is 33 mol% or more and 60 mol% or less, and the side chain has acrylium or methacrylmethyl groups of 0.01 mol% or more and 1.50 mol% or less; an unsaturated monocarboxylic acid or a salt thereof ( B) is at least one selected from the group consisting of acrylic acid, methacrylic acid, sodium acrylate and sodium methacrylate; modified polyvinyl alcohol (A) / unsaturated monocarboxylic acid in the composition (D) The mass ratio of the salt (B) is 82/18 to 99.9 / 0.1. This makes it possible to provide a modified polyvinyl alcohol-containing composition having excellent performance as a dispersion stabilizer for suspension polymerization of a vinyl compound even after a long period of time has passed after production. |
