| titleOfInvention | Method for producing vinyl chloride polymer |
| abstract | An object of the present invention is to provide a method for producing a vinyl chloride polymer capable of producing a vinyl chloride polymer having good anti-initial coloring property with high productivity. A vinyl chloride monomer or a mixture of another monomer copolymerizable with the vinyl chloride monomer is subjected to suspension polymerization using an oil-soluble polymerization initiator in an aqueous medium. In the method for producing a vinyl polymer, The oil-soluble polymerization initiator is (A) t-amyl peroxy neodecanoate and (B) an organic peroxide other than (A), and a 0.1 mol / liter trichloroethylene solution. And the organic peroxide having a 10-hour half-life temperature of 30 ° C. to 55 ° C. and a polymerization conversion of 65% to 90% when the reaction temperature in the polymerization reactor rises. A method for producing a vinyl chloride polymer, comprising: starting the temperature, raising the temperature by 5 to 30 ° C., and subsequently adding an antioxidant. [Selection diagram] None |
