| titleOfInvention | Method for producing styrene resin |
| abstract | PROBLEM TO BE SOLVED: To improve a processability, a process stability and a mechanical property of a resin, and to produce a styrene resin having a very small amount of elution or volatilization due to a low content of a low molecular component with a high production efficiency. And so on. SOLUTION: A raw material system having the following composition (A) is continuously charged from one side of a reaction vessel R1 having a reverse mixing flow, and the production system is continuously charged from the other side of the reaction vessel R1. The internal temperature of the reaction vessel R1 is reduced to 60 by removing the heat of polymerization by using a reflux condenser attached under reduced pressure, including a continuous anionic polymerization process of extracting. C. or higher and lower than 80 ° C., and controlling the average ratio of the styrene monomer, cyclohexane-based solvent and styrene polymer present in the reaction vessel R1 to the total amount of less than 5% by weight. A method for producing a styrene resin, comprising polymerizing and devolatilizing and drying the obtained styrene polymer solution. (A) Styrene monomer 1.0 kg Cyclohexane solvent 0.5-2 kg Organic lithium compound 0.5-200 mmol. |
