When used in the field, these polymer powders are dissolved in water and provided in the form of an aqueous solution.

溶解時間を要するケースも多い。Problems to be Solved by the Invention During this dissolution operation, since the polymer powder contains fine particles, dust tends to be generated, which is often pointed out as an environmental problem.

よる輸送コスト、保管コストの増大等非経済である。In order to avoid the above-mentioned disadvantages caused by such powder, it is sometimes supplied as a gel-like product with a polymer purity of about 20% by weight. Even when cut, it takes a long time to dissolve because it is difficult to make the particles thinner than powdered products, so they turn yellow. In addition, paste-like products with a polymer purity of 10% or less are also used in some cases, but the common problems with gel-like products and paste-like products include low solid content and increased transportation and storage costs due to low solid content. It is uneconomical.

It may also be possible to use a method such as Usually, when the polymer obtained by the above method is dried in a drying step, hydrogel particles having a water content of 20 to 95% by weight are obtained.

Also, it tends to become "sticky" when dissolved.
尚粒径２１以下とするのは溶解速度を大にする為である
。The reason why the particle size is 21 or less is to increase the dissolution rate.

Among these, especially sorbitan monooleate,
Polyethylene glycol having an average molecular weight of 1000 or more is preferred. As the surfactant, surfactants other than these, inorganic salts, oils, etc. can be further included. This surfactant is effective in preventing caking during storage of hydrogel particles, but if it is less than 500 ppm, caking prevention is insufficient, and this caking also causes "glare" during dissolution. Moreover, if it exceeds 20,000 ppm, the cost will increase and the composition will become sticky, resulting in poor fluidity and poor handling.
このような水溶性高分子組成物の好ましい製造方法とし

子とする。As a preferred method for producing such a water-soluble polymer composition, first, an acrylamide-based polymer is produced in a normal production method with a polymer purity of 20% by weight or more and a particle size of 3 to 10 m.
It is obtained as hydrogel particles of m. This is dried to make the polymer pure content 85 to 95% by weight, and the polymer is finely granulated to a predetermined particle size, and then humidified again to make the polymer pure content 50 to 85% by weight, preferably 60 to 80% by weight. gel particles.
このようにポリマー純分を一旦８５〜８５重量％まで乾
燥した後、再びポリマー純分５０〜８５重量％に加湿す
るのは該ポリマーは含水ゲル状に於て極めて細粒化し難
い為である。The reason why the polymer is once dried to a pure polymer content of 85 to 85% by weight and then humidified again to a pure polymer content of 50 to 85% by weight is that it is extremely difficult to make fine particles of the polymer in the form of a hydrous gel.

よって容易に２ｎｍ以下の粉体に粉砕される。That is, in a normal manufacturing method, the polymer purity is, for example, 20 to
The 35% by weight hydrogel particles are cut into particles with a particle size of 3 to 10 m using a cutting machine, preferably a cutter mill, or a meat chopper.
The polymer is cut into fine particles, and then dried until the polymer purity reaches 85 to 95% by weight. These dry gel particles are easily ground into powder of 2 nm or less by a grinder.

られる。When a predetermined amount (amount required to contain 500 to 20,000 ppm based on the pure polymer content) of a surfactant and water are added separately or as an aqueous solution to the pulverized product obtained as above and kneaded. The dried gel particles absorb water and become gel-like, and the fine powders finer than about 9.1 mm stick together and are granulated, resulting in a non-dusty granule of 2 mlI+ or less as a whole. The surface is almost coated with the surfactant, preventing caking to preserve the surface, making it easy to handle, and providing a product with excellent solubility.
