| titleOfInvention | Method for producing vinyl chloride polymer |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing a vinyl chloride polymer having a high porosity particle structure, excellent processability, and low fish eyes with high production efficiency. SOLUTION: When producing PVC in a reactor having a reflux condenser, the degree of saponification is at least 65 mol% and the average degree of polymerization is 50. 0.01 to 0.2 parts by weight of PVA of 0 to 4000, and a saponification degree of 15 to 54 mol% and an average polymerization degree of 100 to Polymerization is started in the presence of 0.01 to 0.2 parts by weight of PVA of 1500, and at a conversion of 3 to 40%, cooling by the reflux condenser is started, and the degree of saponification is 97 mol% or more. A method for producing PVC, wherein PVA having an average degree of polymerization of 1500 or more is added. |
