PURPOSE:To obtain the titled polymer efficiently, by adding a heat-decomposable initiator and one component of a redox initiator system to an aqueous solution of a cationic monomer, blowing air into the solution, and adding the remaining components of the redox initiator system to initiate the polymerization of the monomer. CONSTITUTION:A heat-decomposable polymerization initiator [e.g., 2,2'-azobis(2- amidinopropane hydrochloride)] and one component of a redox initiator system (e.g., an oxidizing agent component such as an aqueous hydrogen peroxide solution) to an aqueous solution of a cationic monomer (e.g., dimethylaminoethyl methacrylate quaternized with methyl chloride), and air is blown into the solution at a pH of 2-5 to heighten the dissolved oxygen concentration forcibly. The remaining components of the redox polymerization initiator system (e.g., a reducing agent component such as Rongalit) are added, and the solution is cast preferably on an endless belt and polymerized in the presence of atmospheric air to obtain the purpose water-soluble cationic polymer in the form of, for example, a sheet.

Normal aqueous solution polymerization is a method that consists of charging a highly concentrated monomer aqueous solution into a polymerization tank, adjusting the temperature to a certain temperature, deoxidizing the inside of the polymerization tank by so-called nitrogen purge, and then adding a polymerization initiator. It is carried out by This method is based on so-called patch work1, and there are various problems in making it continuous. In other words, an example of polymerization is the one described in Japanese Patent Application Laid-Open No. 1/-11/-30, which is a continuous method using an endless belt, but does not require the infiltration of oxygen, which interferes with polymerization. In order to prevent this, it is necessary to place the entire polymerization apparatus under a nitrogen atmosphere, which not only increases the size of the apparatus but also complicates its maintenance. On the other hand, as a method suitable for serialization, JP-A-5J-/J&! Belt polymerization methods using ultraviolet rays, such as those described in Publication No. 1, are known. This method is suitable for rapid polymerization and continuous operation, but since it is necessary to uniformly irradiate the entire monomer aqueous solution with ultraviolet rays, the monomer aqueous solution must be formed into a film, and therefore, industrially, a large polymerization area is required. I have to say.

Effects According to the present invention, one component (for example, an oxidizing agent) of a thermal decomposition type initiator and a redox type initiator is added to an aqueous solution of a cationic monomer.
When air is blown into the solution at pH j~j, the solution remains for a short period of time, for example, at room temperature at least 8. Mo2
It is stable for 1 hour, and when the remaining components of the redox type initiator (i.e., reducing agent) are added to this, the polymerization system can be stabilized for a relatively short period of time, e.g., 30 to 60 minutes, without deoxidizing the polymerization system. Polymerization begins. Furthermore, the polymerization initiated in this manner does not suffer from the problem of premature termination of polymerization, which is often observed in atmospheric polymerization, and the resulting polymer has good solubility.

Therefore, a non-catisine monomer can be used in combination within the range (generally in a small amount) that the resulting polymer can be said to be a "water-soluble cationic polymer". It goes without saying that the cationic monomer must be water-soluble to the extent that it can form a predetermined aqueous solution. It is well known that the generation is caused by thermal decomposition, and an appropriate one may be selected and used in the present invention. Pyrolytic initiators whose decomposition temperature is too high compared to the temperatures expected during polymerization may not be suitable. The initiator should also be sufficiently water soluble to initiate aqueous polymerization.

The polymerization method that makes the best use of the features of the present invention consists of casting a prepared cationic monomer solution on an endless track to initiate polymerization, and obtaining a plate-shaped polymerized product. Here, "starting polymerization by casting" includes not only starting polymerization after casting but also starting casting after starting polymerization. Therefore, the remaining components of the redox-type initiator are added to the prepared monomers by suitable means, such as line mixing using a screen, and this aqueous solution is added to the track before or after the start of the polymerization. to spread.

It is desirable to pay attention to the material or surface properties of the endless belt and other parts that come into contact with the produced coalescence in order to facilitate the peeling of the polymer (the produced polymer is in the form of a gel, so its concentration should be (In some cases, peeling from the belt may be defective.) Equipment with a fluororesin lining is most preferred; however, stainless steel equipment is sufficient if a release agent such as silicone is used.
In the present invention, unlike the case of photopolymerization, the depth of the monomer aqueous solution, that is, the thickness of the resulting polymer gel, is not subject to any restrictions from the viewpoint of the polymerization method, but from the viewpoint of endless belt production. There are restrictions, and it is usually about 50 to 100 mm.
