| titleOfInvention | Dispersion stabilizer for suspension polymerization of vinyl compound |
| abstract | The invention discloses a dispersion stabilizer for suspension polymerization of a vinyl compound comprising a vinyl alcohol polymer (A) having a content of an ethylene unit of 0.5 to 10 mol%, a degree of saponification of 60 mol% or more and a degree of polymerization of 600 or more and a vinyl alcohol polymer (B) selected from a vinyl alcohol polymer (B1) having a content of an ethylene unit of 0.5 to 10 mol%, a degree of saponification of 20 to 80 mol% and a degree of polymerization of 100 to 600, a vinyl alcohol polymer (B2) having a degree of saponification of 20 to 60 mol% and a degree of polymerization of 100 to 600 and a vinyl alcohol polymer (B3) having a content of an ethylene unit of 0.5 to 10 mol%, a degree of saponification of 90 mol% or more and a degree of polymerization of 1,000 or more. Further, the invention discloses a process for suspension polymerization of a vinyl compound using the dispersion stabilizer for suspension polymerization. The dispersion stabilizer for suspension polymerization of the vinyl compound in the invention, by the use of a small amount, exhibits quite an excellent suspension polymerization stability. Further, the suspension polymerization of a vinyl compound using this dispersion stabilizer can produce porous vinyl polymer granules having a sharp particle size distribution and a high bulk density. In the polymer granules, a rate of plasticizer absorption is high to give a high processability, a monomer remaining in polymer granules is easy to remove, and fish eyes in a molded product are decreased in the molding. |
