Abstract
A polymer composition, a process for the production of a polymer composition, in particular of an absorbent, are disclosed which substantially consist of a special component A based on renewable polysaccharide raw materials, a special component B consisting of a water-soluble polymer, a matrix material, an ionic and/or covalent cross-linking agent, or an anti-blocking agent, which is obtainable in that the water-swellable polymer is brought together with the polysaccharide polymer, that these are dried and ground then, the other components are added, and mixing up to homogeneity is effected followed by a heat treatment, and that during the addition of the cross-linking agent, after said heat treatment, the same is optionally fixed by the matrix by means of a final heat treatment. Additionally the use of this polymer composition and (animal) hygiene items and chemico-technical products are disclosed which comprise a previously manufactured polymer composition.
