Abstract

A polymer composition, in particular an absorbent composition or an active substance-containing depot material are disclosed which substantially consist of a water-soluble and/or water-swellable polymer based on polysaccharides as the main component, and of a water-swellable polymer as further component, used as polymeric components, and of a matrix material for the prevention of separation and gel blocking, an ionic or covalent cross-linking agent, a reactive additive, as well as of an anti-blocking agent. Additionally, their production and use as well as (animal) hygiene items and chemico-technical products are disclosed which comprise these polymer compositions or absorbent compositions.
