Description

200808878 IX. OBJECTS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a water-absorbing polymer structure, a method for producing a water-absorbing polymer structure, a water-absorbent polymer structure obtainable by the method, and a water-absorbent polymerization. a composite of a structure and a substrate, a method for producing a composite, a composite obtainable by the method, a chemical product comprising a water-absorbing polymer structure or a composite, and a water-absorbing polymer structure or composite in a chemical product Use in the middle. [Prior Art] The absorbent is a water-insoluble cross-linked polymer capable of absorbing a large amount of an aqueous liquid, particularly a body fluid, preferably urine or blood, by swelling and forming a hydrogel, and retaining under a predetermined pressure. It. Because of these characteristic properties, some polymers are primarily provided for use by incorporation into hygiene articles such as, for example, baby diapers, incontinence products, or feminine hygiene products. The manufacture of the collector and the collector is usually carried out by radical polymerization of a monomer carrying an acid group in the presence of a crosslinked sword. In this method, polymers having different absorption properties can be produced by selecting the monomer composition, the crosslinking agent, and the polymerization conditions and the process conditions of the hydrogel obtained after the polymerization. Further, the monthly b-type is provided by the production of a graft polymer, for example by the use of chemically modified starches, celluloses and polyvinyl alcohols according to DE-OS 26 12 846 and, for example, according to DE 40 20 780 The surface of the polymer particles is crosslinked after C1 to post-treat the hydrogel or the powdery polymer particles obtained after drying the hydrogel. The post-crosslinking by the surface of the water-absorbing polymer particles, particularly the polymer particles, increases in the absorption capacity under the pressure effect. 200808878 In order to be aesthetically pleasing and because of the reasons for the ring, the design of smaller and thinner sanitary products is on the rise. In order to achieve a fixed total reserve capacity of sanitary products, this demand can only be met by reducing the proportion of large batt. Therefore, the water-absorbing polymer gradually forms a main component of the sanitary article. The superabsorbent known from the prior art, for example from DE 40 20 780 C1, is usually white. However, 'this has the disadvantages of white superabsorbent particles which adversely affect the appearance of colored sanitary articles in colored sanitary articles which are preferably used in the corresponding color-matched undergarment group, especially if a large amount of superabsorbent particles are used. . In addition to the disadvantages of white superabsorbent particles which undesirably affect the appearance of colored sanitary articles, superabsorbents known in the art are often not sufficiently effective to adhere to unpleasant odor compounds in body fluids. For this reason, US 2 〇〇 4/〇 12681 suggests coating the surface of the substrate contained in the absorbent article with the active material and the activating reagent, and then heating to 1 Torr. (a temperature between 3 and 300 00 c, whereby the polymeric material is converted to activated carbon by an activating reagent and heating. The activated carbon formed in this manner can adsorb an unpleasant odorous compound. However, this method is A disadvantage of odor control is that, for example, the surface of the substrate sensitive to temperature increase cannot be coated with activated carbon in this way. A further disadvantage is that in the case of a diaper as an absorbent member, the activated carbon coating is due to the diaper wearer. The invention is rubbed off to cause it to appear outside the diaper. [Invention] The present invention has the object of overcoming the disadvantages caused by the prior art. The present invention particularly has a superabsorbent or a composite 200808878 comprising a superabsorbent. The objects, especially their characteristics, are in their products without aesthetic disadvantages. They can also be used in coloring hygiene according to the invention, and should not only be provided for use in colored hygiene products. There is no aesthetic disadvantage _ > , superabsorbent or superabsorbent-containing composite, and these superabsorbents or some of the extracts are also Should not be as special as possible in the specific example. #仏★ j This effectively binds an unpleasant odor compound, which is especially white in the body fluid or it will be transparent.

Produced by bacteria that decompose compounds contained in body fluids. Despite the advantages described above, these superabsorbents or composites each comprising a superabsorbent should have good skin tolerance and other excellent absorbent properties.
