Abstract:
The invention relates to a process for immobilizing 2-bromo-2-nitro-1,3-propanediol by producing a mixture of water-absorbent polymer particles and 2-bromo-2-nitro-1,3-propanediol, in which the mixture additionally contains a compound with at least two epoxy groups and the mixture temporarily has a temperature of at least 40°C.
Abstract:
The invention relates to deodorizing compositions which contain water-absorbing polymer particles and metal peroxides, and to the production thereof.
Abstract:
The invention relates to a method for producing deodorizing water-absorbing polymer particles based on ethylenically unsaturated, acid group-carrying monomers, the polymer particles being coated with a chelating agent and a tannin.
Abstract:
The formation of unpleasant odours from bodily fluids in hygiene articles is reduced or prevented when a composition, which is used in the hygiene articles, contains at least one keto acid in addition to a super absorber.
Abstract:
Aqueous dispersions of water-soluble and/or water-swellable anionic polymers which are obtainable by free radical polymerization of ethylenically unsaturated, anionic monomers in an aqueous medium in the presence of at leas one stabilizer, the polymerization being carried out in the presence of at least one water-soluble polymer of the groups consisting of (a) graft polymers of vinyl acetate and/or vinyl propionate on (i) polyethylene glycols or (ii) polyethylene glycols or polypropylene glycols blocked at one or both terminal groups with alkyd carboxyl or amino groups, polyalkylene glycols, polyalkylene glycols blocked at one or both terminal groups with alkyl carboxy or amino groups and (b) water-soluble copolymers of (b1) nonionic monoethylenically unsaturated monomers, (b2) cationic monoethylenically unsaturated monomers and if appropriate (b3) anionic monoethylenically unsaturated monomers, the fraction of the interpolymerized cationic monomers being greater than that of the anionic monomers, as a stabilizer, said aqueous dispersions are prepared by free radical polymerization of the anionic monomers in an aqueous medium in the presence of the abovementioned water-soluble polymers (a) and (b) and said aqueous dispersions are used as thickeners for aqueous systems.
