The present invention relates to a process for the production of a superabsorber, comprising as steps providing a water-absorbing polymer structure, bringing the water-absorbing polymer structure into contact with a modifying agent, preferably a modifying agent, and the further treatment of the water-absorbing polymer structure which has been brought into contact with the modifying agent. The further treatment is carried out at least partly in a rotating container. The invention furthermore relates to a device for the production of a superabsorber, superabsorbers, a composite, a process for the production of a composite, the composites obtainable by this process, chemical products, such as foams, shaped articles or fibers, and the use of a superabsorber.

Process for gentle mixing and coating of superabsorbers

The present invention relates to a pulverulent polymer post-crosslinked on the surface and absorbing water or aqueous liquids, synthesised from polymerised, optionally pre-crosslinked monomers containing partially neutralised carboxyl groups. The present invention also relates to a process for the post-treatment of the aforementioned polymers and the use of a solution of at least one salt of an at least trivalent cation for restoring the gel permeability of the aforementioned polymers that have been damaged by mechanical action.

The present invention relates to anhydrous and water-containing agents for waterproofing leathers and furs, which comprise a silicone and as emulsifier an alkyl polyalkylol ether carboxylic acid and/or an alkylaryl polyalkylol ether carboxylic acid and/or one of their alkali, alkaline earth, ammonia, amine, or alkanolamine salts. The present invention further relates to the use of these agents for waterproofing, preferably in retanning or afterwards. Subsequent to the waterproofing, an aftertreatment using metallic salts of bito tetravalent cations may be carried out.
