The invention relates to crosslinked polymerizates which are capable of absorbing, which are based on partially neutralized, monoethylenically unsaturated monomers that carry acidic groups, which exhibit improved properties, in particular, with regard to their ability to transport liquids when in a swollen state, and which have been subsequently crosslinked on the surface thereof with a combination consisting of an organic crosslinker compound, with the exception of polyols, and of a cation provided in the form of a salt in an aqueous solution.

Powdery, cross-linked absorbent polymers, method for the production thereof, and their use

The present invention concerns highly swellable absorption mediums with a reduced caking tendency at high humidity and/or high temperatures, wherein a swellable polymer is coated with a non-ionic, nitrogen-containing surfactant and optionally a Lewis acid and then reacted by heating.

Highly swellable absorption medium with reduced caking tendency

The invention describes superabsorbent polymers composed of surface-post crosslinked polycarboxypolysaccharides having excellent age-stable absorption properties, even under load, high attrition resistance and biodegradability and their use for absorbing water, aqueous or serous fluids and also blood. Also disclosed is a method of making which is impervious to changes in raw material quality and which provides consistent product quality.

Preparation of superabsorbent polymers

The invention relates to absorbent, cross-linked polymers based on partially neutralized, monoethylenically unsaturated monomers that bear acidic groups. Said polymers exhibit improved properties with regard to their ability to transport liquids in a swollen state. The surface of the polymers is postreticulated, using a combination of an organic cross-linking compound, excluding polyols, and a cation that is in salt form in an aqueous solution.

Pulverulent, cross-linked polymers capable of absorbing aqueous liquids

The invention describes supersuperabsorbent polymers composed of surface-post crosslinked polycarboxypolysaccharides having excellent age-stable absorption properties, even under load, high attrition resistance and biodegradability and their use for absorbing water, aqueous or serous fluids and also blood. Also disclosed is a method of making which is impervious to changes in raw material quality and which provides consistent product quality.

The invention relates to a pulverulent laundry and cleaning detergents ingredient, to a process for its preparation and to its use.

Pulverulent laundry and cleaning detergent ingredient consisting of polycarbosylate and silicate

Powdery, cross-linked absorbent polymers method for the production thereof and their use

The invention relates to absorbents for water and aqueous liquids, which absorbents are based on water-swellable, yet water-insoluble polymers wherein zeolites high in silicon have been incorporated ionically and/or as a result of mechanical inclusion.

Water-absorbing polymers having interstitial compounds, a process for their production, and their use

The invention relates to absorbent polymers based on optionally partially neutralised, monoethylenically unsaturated, acid group-carrying monomers. The surfaces of said polymers are re-cross-linked. The inventive polymers also have cyclodextrines and/or cyclodextrine derivatives which are covalently and/or ionically bonded and/or included therein.

The invention relates to absorptive, crosslinked polymers which are based on partly neutralized, monoethylenically unsaturated monomers carrying acid groups, and have improved properties, in particular in respect of their capacity for transportation of liquids in the swollen state, and which have been after-crosslinked on their surface at temperatures of at least 150&deg; C. with a combination of polyol as after-crosslinking compound and a cation in the form of an aqueous solution.

Pulverulent, crosslinked polymers which absorb aqueous liquids and blood

The invention relates to water-soluble homopolymers and copolymers, which comprise an EbC50 value according to the algae toxicity test of <i> Scenedesmus subspicatus</i> of grater than 10 mg/l. The invention also relates to the production and use of these polymers as flocculation aids or thickeners and as a constituent of a plant protective agent or of an erosion protective agent.

Water-soluble homopolymers and copolymers having an improved environmental acceptability

The invention relates to absorvents for water and aqueous liquids, which are vased on water-swell-able, yet water-insoluble polymers wherein cyclodextrin or cyclodextrin derivatives and zeolites high in silicon have been incorporated ionically, covalently and/or as a result of mechanical inclusion.
