When the reaction product has viscoelasticity or gel like consistency, it can be efficiently discharged. For example, this reactor is suitable for preparing an acrylic acid based or acrylamide based polymer with a high mol. wt.

That is, in a state where the reaction product is filled in the apparatus, the inlet at one end and the outlet at the other end are opened, and the liquid reaction raw material is press-fitted through the inlet at one end. The injection pressure of the raw material may be such that the partition moves, and is controlled by the amount and properties of the product. This injection pressure moves the partition to the other end side, and the reaction product is discharged from the discharge port at the other end. At this time, since the raw material and the product are partitioned by a partition, the raw material does not short pass or the raw material and the product are not mixed as in the conventional case. Further, since the product is pushed out by the movement of the partition, it can be discharged smoothly without being unevenly discharged as in the conventional case. Particularly, when the product is a gel-like product having viscoelasticity, the product can be discharged smoothly and efficiently. When the raw material is filled in the device, the entire amount of the product can be discharged. However, when it is used for a reaction in which the reaction liquid expands, it is preferable to fill a compressive inert gas at the final stage of the raw material injection instead of press-fitting a part of the raw material. By enclosing this gas, it is possible to mitigate a rapid pressure increase due to the expansion of the reaction liquid which is an incompressible fluid. After the injection and the accompanying discharge are completed, the opened inlet and outlet are closed, and the inside of the apparatus is hermetically closed to perform the next reaction. After the completion of this reaction, since the partition has moved to the other end side, the raw material is further injected from the other end side, and the product is discharged from the opposite side by this injection pressure. In this way, the inlets and the outlets at both ends are used alternately, and the reciprocating movement of the partition is not wasted at all.

Examples of the shape of the reaction tank 1 include a horizontal shape in which the cylinder is straight or curved in a U-shape with a constant radius of curvature, and a vertical shape in which the cylinder is straight. Of these, a straight tube shape as shown in FIG. 1 is particularly preferable. The shape of the cross section of the cylinder is arbitrary, and may be, for example, a square, a circle, or an ellipse. The size of the reaction tank 1 is not particularly limited. The material and wall thickness of the wall surface of the reaction tank 1 are not particularly limited, and may be selected in consideration of the corrosion resistance to the raw materials and reaction products to be charged, the pressure applied in the device, and the like. Examples of this material include stainless steel, glass lining steel, resin (Teflon etc.) lining steel, and the like. Further, it is preferable that the inner wall surface has high smoothness (for example, a surface polished by electrolytic polishing or a Teflon-lined surface).

において用いられるシール方法を適用できる。In FIG. 1, reference numeral 2 is a partition which can reciprocate. The partition may have any shape as long as it does not fall over when reciprocating and does not leak liquid to the opposite side. In addition, it is preferable to match the shapes of both lateral surfaces of the partition with the shapes of the inner wall surfaces of both ends of the reaction tank in order to discharge the product without leaving it. The partition is also required to have a weight that does not hinder the reciprocating motion. A typical example of a partition satisfying these conditions is that the portion in contact with the inner wall surface as shown in FIG. 1 has a certain width, the inside is hollow, and the shape of both lateral surfaces is the shape of the inner wall surface at both ends of the reaction tank. It is a partition according to. The material of the partition may be a material that is not too heavy and has a corrosion resistance against the raw materials and products to be added. For example, the same material as the material of the wall surface of the reaction tank 1 exemplified above can be used. Practically important is the liquid sealability between the partition and the inner wall surface. As a sealing method, a piston ring, a Teflon gasket, or in some cases, an O-ring, a V-ring packing, or the like, which is normally used in reciprocation, can be used.

These may be openable / closable inlet / outlet ports, but since the raw material and the product usually have different properties such as viscosity, it is better to provide the inlet port and the outlet port separately. The method of opening and closing each of the inlet and the outlet is not particularly limited, and for example, a valve system as shown in FIG. 1 can be mentioned. 5
