Method for producing acrylonitrile-based (co) polymer |
| abstract |
The present invention relates to a method of (co) polymerizing a monomer containing at least an acrylonitrile-based monomer as an essential component at a temperature of 80 ° C or higher while evaporating the monomer by bulk or solution polymerization, wherein the upper portion of the lower polymerization liquid in the reaction tank is When the gas phase portion is formed in the gas, the temperature of the gas phase is maintained at 30 to 65 DEG C, and the polymerization method of the (co) polymer is characterized by polymerizing substantially without evaporating steam from the lower polymerization solution to the outside of the reaction tank. In the present invention, by cooling the reaction vessel upper part and maintaining the temperature at a specific temperature, the polymerization of the unreacted monomer in the gas phase part is suppressed and the gelled polymer is not incorporated into the product. The reaction heat of the city can be removed efficiently. |
