| titleOfInvention | Modified vinyl alcohol-based polymer, dispersion stabilizer for suspension polymerization, method for producing vinyl resin, and method for producing modified vinyl alcohol polymer |
| abstract | The present invention provides a dispersion stabilizer for suspension polymerization that satisfies the following requirements during suspension polymerization of vinyl compounds: (1) fewer coarse particles in resin particles; (2) obtaining resin particles with as uniform particle diameter as possible, Prevent scale adhesion; (3) Obtain a resin with high porosity. As a result, the removal of monomer components becomes easy, and it becomes a resin with high absorbency of plasticizer. The modified vinyl alcohol polymer of the present invention has a polyoxyalkylene unit represented by the general formula (I) in a side chain and a carbonyl unit represented by the general formula (II) at a terminal of a main chain. The total number of moles of the monomer units constituting the main chain of the modified vinyl alcohol polymer and the number of moles of the aforementioned monomer units having a polyoxyalkylene unit represented by the general formula (I) in the side chain. The ratio is 0.01 mol% to 5 mol%, and the ratio of the mol number of the carbonyl unit represented by the general formula (II) is 0.01 mol% to 0.5 mol%. |
