| titleOfInvention | Process for producing vinyl chloride polymer |
| abstract | A process for producing a vinyl chloride polymer which comprises suspension-polymerizing a vinyl chloride monomer or a mixture of a vinyl chloride monomer and a monomer copolymerizable therewith in a polymerization vessel equipped with a reflux condenser, wherein (A) during a certain time in the period from initiation of heat removal by the reflux condenser to termination of the polymerization, a highly active oil-soluble polymerization initiator having a 10-hour half-life temperature of 40°C or lower as measured in benzene in a concentration of 0.1 mol/L is added to the reaction mixture and (B) at least throughout the period from initiation of the addition of the highly active oil-soluble polymerization initiator to termination thereof, an antioxidant is continuously or intermittently added to the reaction mixture. Thus, a process for producing a vinyl chloride polymer through aqueous-suspension polymerization in a polymerization vessel equipped with a reflux condenser can be improved. The ability to remove heat can be efficiently utilized to attain a reduction in polymerization time. In addition, a vinyl chloride polymer of satisfactory quality extremely reduced in fish eyes can be produced. |
