Description of the Related Art As a conventional apparatus, for example, an extruder is used for modifying a polymer or synthesizing a polymer as described in a literature (Plastic Vol. 41 No. 7 P39 to P42). Although an extruder is suitable for processing a high-viscosity liquid, the residence time required for the polymerization reaction could not be provided for the synthesis of a polymer that requires a reaction time because the residence time is generally short. In addition, there is a method of increasing the axial length of the extruder in order to lengthen the residence time, but it is difficult to satisfy the residence time required for the reaction due to restrictions on the structure of the apparatus. Therefore, in order to secure the residence time necessary for the reaction, a plurality of extruders are connected in series to secure the residence time. With such a configuration, there is a drawback that the installation space of the device becomes large and the cost of the device becomes expensive.

方向に数個所設けると前述の効果がさらに有効となる。The operation of this embodiment having the above configuration will be described. The object to be processed supplied from the inlet 5 of the liquid to be processed is changed into a high-viscosity fluid by the heat supplied from the main body 1 and the heat of stirring of the stirrer 8. The high-viscosity fluid is sheared and agitated when passing through the gap D 1 between the agitator 8 and the main body 1. When the gap D 1 between the stirring body 8 and the main body 1 is constant, the flow rate of the liquid to be treated is determined depending on the rotation speed of the stirring body. When polymer alloying or polymer blending is performed using such an apparatus, in order to secure the residence time of the apparatus, the rotational speed is reduced and the flow rate of the liquid to be treated is reduced to operate. However, in this method, since the rotation speed is lowered, the shearing force applied to the liquid to be treated is lowered, the stirring performance is deteriorated, and the quality of the product is lowered. Therefore, if the gap between the agitator 8 and the main body 1 is increased from D 1 to D 2 , the volume of the device to be treated increases in the enlarged portion and the residence time can be increased. Further, in this portion, the shearing force changes intermittently due to the presence of the upper portion having a wide gap and the lower portion having a narrow gap, which gives the liquid to be treated a good stirring action. Furthermore, the above-mentioned effect becomes more effective when such a portion is provided at several places in the axial direction of the stirring body 3.

In the present embodiment, an air supply port 7 for removing volatile matter generated in the space 2 enlarged by the agitator 8 and the gap adjusting unit 4 is provided. When the gap between the agitator 8 and the main body 1 of the liquid to be treated is increased from D 1 to D 2 , the amount of the liquid to be treated in the space 2 increases. When the pressure is reduced in order to remove the volatile matter in this portion, the liquid to be treated becomes a foaming state. If the volume of the space portion 2 is increased at this time, the fired state becomes a good load, and defoaming can be completed in a short time.

In this embodiment, the agitator 8 and the gap adjuster 4 are provided with a space 2 enlarged by the agitator 8 and a plurality of air supply ports 7 for removing the volatile matter generated in the space 2. The height with 4 is set to a height different from D 2 and D 3 . The respective positions of the space 2 are determined according to the reaction status of the substance to be processed and the processing status, and the set height is also determined. With such a structure, volatile matter can be efficiently removed according to the reaction situation.
