| titleOfInvention | Method for producing vinyl chloride polymer |
| abstract | (57) [Summary] [Purpose] To produce a vinyl chloride polymer with excellent quality such as fish eyes and particle size without causing scale adhesion to the inner wall of the polymerization vessel and sludge and scale adhesion to the heat transfer surface of the jacket. A method for manufacturing with high productivity is provided. [Structure] A vinyl chloride monomer selected from a vinyl chloride monomer or a mixture of a vinyl chloride-copolymerizable monomer and vinyl chloride is added to an aqueous medium in the presence of a polymerization initiator and a surfactant. In the polymerization at a temperature of 40 to 70 ° C. in which the temperature of the water and the monomer charged in the polymerization vessel is raised to a predetermined polymerization temperature, an inner jacket type polymerization in which a passage for a cooling / heating medium is provided on the inner surface of the polymerization vessel main body Using a vessel, the temperature (Θ) of the heat medium circulated in the jacket is adjusted so that T + 5 ≦ Θ <80 (° C.) with respect to a predetermined polymerization temperature (T), and the temperature is raised, and then polymerization is carried out. |
