A polymer composition, in particular an absorbent material composition or an active substance-containing depot material, substantially consists of a water-soluble and/or water- swellable polymer based on polysaccharides as main polymer component and a water- swellable polymer as additional polymer component. The composition also contains a matrix material to prevent dissociation and gel blocking, an ionic or covalent cross-linking agent, a reactive additive and an antiblocking agent. Also disclosed is the production and use of this composition, as well as hygiene products (for animals) and technical chemicals containing said polymer compositions or absorbent material compositions.
Une composition polymère, notamment une composition de matériau absorbant ou d'un matériau de dépôt contenant une substance active, comprend comme composant polymère principal un polymère soluble et/ou gonflant dans l'eau à base de polysaccharides et comme composant polymère additionnel un polymère gonflant dans l'eau. La composition comprend également un matériau matriciel qui empêche la dissociation et le blocage par gel, un agent réticulant ionique ou covalent, un additif réactif et un agent anti-blocage. L'invention concerne en outre leur production et leur utilisation, ainsi que des produits sanitaires (pour animaux) et des produits chimiques industriels contenant ces compositions polymères ou ces compositions de matériau absorbant.
