Method for producing vinyl chloride polymer |
| abstract |
PROBLEM TO BE SOLVED: To prevent adhesion of a polymer scale to a surface or the like of a baffle facing an inner wall of a polymerization vessel, which has been difficult in polymerization in an aqueous medium in a polymerization vessel such as vinyl chloride. And a process for producing a vinyl chloride-based polymer from which a high-quality polymer product with little initial coloring is obtained. SOLUTION: When a vinyl chloride monomer or a vinyl monomer mixture containing the monomer as a main component is polymerized in an aqueous medium using a polymerization initiator, when producing a vinyl chloride polymer, The polymerization is carried out in the presence of a chelating agent capable of chelating Fe (II) or Fe (III). |
