| titleOfInvention | Process for producing vinyl resin |
| abstract | There is disclosed a process for producing a vinyl resin by suspension polymerization of a vinyl compound in the presence of a suspending agent (A) which comprises using a polymerization vessel equipped with a reflux condenser and adding a polyvinyl alcohol (B) having a degree of hydrolysis of at most 85 mol% in an amount of 0.001 to 0.5 part by weight based on 100 parts by weight of said vinyl compound when a polymerization conversion is in the range of 30 to 90%. According to the present invention, there is provided a process for producing a vinyl resin having a high bulk density, which is excellent in anti-foaming effect against the dry foam being generated in the middle to latter period of the suspension polymerization in a polymerization vessel equipped with a reflux condenser which is excellent in productivity. |
