    Abstract: A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.

    Abstract: A process for binding particulate water-absorbing acid-functional polymers to a carrier material by means of compounds comprising amino groups, which comprises contacting the carrier material with particulate water-absorbing acid-functional polymers whose acid groups have been 0 to not more than 55 mol % neutralized with alkali metal and/or ammonium bases and then raising the degree of neutralization of these polymers to not less than 60 mol % by treatment with amino-containing compounds. The use of compounds comprising amino groups and selected from the group of the compounds consisting of the alkanolamines and compounds which contain ethyleneimine and/or vinylamine units to neutralize and bind particulate water-absorbing acid-functional polymers neutralized 0 to not more than 55 mol % with alkali metal and/or ammonium bases to a carrier material.
