本発明は、市・に体液（尿、汗、経１（１等）に対して

ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polymer composition having an excellent absorption ability for body fluids (urine, sweat, etc.).

水性を第１ｊＪ１１する種々の用途に使用され。In recent years, superabsorbent polymers have been used for a variety of purposes including sanitary products such as sanitary products, diapers, water retention agents, and other uses that require water absorption and water retention.

当該産業分野の大きな課題となっている。Under these circumstances, various types of superabsorbent polymers are currently being developed, such as starch-based, polyacrylate-based, modified polyvinyl alcohol-based, and cellulose-based polymers.
These polymers exhibit an Lfc absorption capacity of about 500 to 1,000 times their own weight for ion-exchanged water, but an absorption capacity of 50 to 60 for ionic aqueous solutions.
This is about twice as much, which is a significant drop. However, in real life, most of these absorbent polymers are used for ionic aqueous solutions such as body fluids, so their absorption capacity is insufficient, and their absorption capacity in ionic bath fluids is insufficient. ”2 has become a major issue in this industrial field.
本発明者らは、かかる技丙的３課題解決のため。The present inventors aimed to solve these three technical problems.

組成物を得ることが出来る。If we list the excellent features of the present invention, first and foremost, as mentioned above, we can mention the convenience of the manufacturing method by 1 meter. That is, the conventional production process for absorbent polymers requires chemical reactions such as copolymerization reactions including graft polymerization, crosslinking reactions, saponification reactions, and neutralization reactions, but according to the present invention, the constituent components A polymer composition with a desired absorption capacity can be obtained by simply mixing and stirring the polymer in an aqueous solution, heating and cooling if necessary.

リマーのゲルイ４造は、共イ１結合あるいは。Furthermore, the polymer composition that can be produced from just one product is very 4N efficient when discarded or disposed of after use. In other words, the conventional absorbent polymer has a four-structured gel-like structure, a co-yellow-one bond, or a double-bonded structure.

リマーをｙｌｌいた場合の如き障害を起す心配はない。It has a strong cross-linked structure created by crystallization, and when used in sanitary products, diapers, diapers, etc., it can cause problems such as clogging pipes when disposed of after use. Therefore, they cannot be flushed down the flush toilet, and this is one of the major reasons why products using absorbent polymers are less likely to be used in real life, despite their great usefulness. On the other hand, since the gel structure of the polymer + 1itl composition of the present invention has a crosslinked structure mainly due to hydrogen bonds between polysaccharides, the gel after water absorption easily separates from the gel-like substance in hot water. After converting into a sol, if it is washed away with a large amount of water, it will not gel again and there is no need to worry about the problems that would occur when conventional absorbent polymers were used.
