| titleOfInvention | Unreacted monomer recovery method |
| abstract | (57) Abstract: A vinyl chloride monomer or a monomer mixture mainly composed of vinyl chloride is polymerized in an aqueous medium in a polymerization vessel in the presence of a polymerization initiator, and then the reaction mixture is left unreacted. When recovering the reacted monomer, an unreacted monomer is recovered from the recovery line while adding a polymerization inhibitor to the unreacted monomer recovery line connected to the polymerization vessel. Method of recovering monomer. According to the present invention, in recovering unreacted monomer after polymerization of vinyl chloride-based monomer, it is possible to prevent scale from adhering to the recovery line or clogging of the recovery line even if repeated recovery is performed. It is possible to prevent the unreacted monomer from being stably recovered over a long period of time, and it is possible to perform a good recovery operation without impairing the productivity and complicating the equipment. |
