Method for producing vinyl chloride polymer |
| abstract |
PROBLEM TO BE SOLVED: To provide a vinyl chloride polymer capable of quantitatively and stably adding an antioxidant dispersion liquid without clogging inside a pump even when the pressure in a polymerization vessel is high. A manufacturing method is provided. SOLUTION: In a polymerization vessel, a vinyl chloride monomer or a monomer mixture containing a vinyl chloride monomer is polymerized in an aqueous medium, an antioxidant is added to the polymerization mixture, and a vinyl chloride polymer is obtained. Is prepared, a dispersion obtained by dispersing an antioxidant in an aqueous medium with a dispersant is added by a uniaxial eccentric screw pump. |
