やすい。As a method for manufacturing rubber-reinforced styrenic resin, there is a method in which a raw material obtained by dissolving reinforcing rubber in a monomer liquid containing a styrene monomer is polymerized by bulk polymerization or solution polymerization (Japanese Patent Application Laid-open No. 63-162). Publication No. 713, JP-A-1-252.
Publication No. 648). In this case, if the reinforcing rubber is not sufficiently dissolved, the piping that transports the raw material to the polymerization process and the filtration device that removes impurities from the raw material may become clogged.
While the raw materials are stored in the tank, undissolved reinforcing rubber may settle in the tank, or the quality of the resulting comb-reinforced styrene resin may become unstable, making it impossible to obtain the desired physical properties. A problem will occur. In particular, when a high viscosity rubber is used as the reinforcing rubber, the rubber tends to be insufficiently dissolved.

For this reason, three or more types of stirring tanks are connected in series, but there are problems such as the equipment becomes large-scale and the residence time in the stirring process becomes long.
