    摘要： Process for preparing fine-particle, water-insoluble polymers of aziridines by polymerizing aziridines, preferably ethylenimine, in the presence of crosslinkers which contain at least two functional groups, and in at least one ether, and also modified, water-insoluble polymers of aziridines which can be obtained by reacting fine-particle, water-insoluble, crosslinked polymers of aziridines, in aqueous medium, with carbon disulfide or formaldehyde and a nucleophilic agent from the group consisting of alkali metal cyanides, primary amines, secondary amines, alkali metal sulfites and alkali metal phosphites, and use of the modified and non-modified fine-particle, water-insoluble polymers for immobilizing active compounds, as absorbents for aldehydes, ketones and acids, and also for removing heavy metal ions from wastewaters.

    摘要： Composite materials comprising at least one natural fiber, at least one thermoplastic polymer, and at least one random copolymer having a molar mass Mn of up to 20,000 g/mol. The random copolymer is produced from the copolymerization of ethylene and at least one comonomer. The comonomer is selected from the group consisting of ethylenically unsaturated C3-C10 monocarboxylic acids; ethylenically unsaturated C4-C10 dicarboxylic acids or their anhydrides; epoxy esters of ethylenically unsaturated C3-C10 monocarboxylic acids, and (b4) comonomers of the general formula I: wherein R1 and R2 are a hydrogen or an unbranched or branched C1-C10-alkyl; R3 is identical or different and is a hydrogen, unbranched and branched C1-C10-alkyl or C3-C12-cycloalkyl, where two radicals R3 may be bonded together to form a 3-10-membered ring; X is an oxygen, sulfur or N—R4; R4 is an unbranched or branched C1-C10-alkyl; and A1 is a divalent group selected from C1-C10-alkylene, C4-C10-cycyloalkylene, and phenylene.

    摘要： A process for producing thin absorbent planar structures which may be used in hygiene products such as diapers, incontinence products, wound contact materials or sanitary napkins to absorb body fluids, comprises the steps of: A) producing a mixture of an adhesive in dispersion form and a particulate absorbent by fluidizing the components, B) applying the mixture of adhesive and absorbent uniformly to the surface of one side of a first planar backing material, C) one side of a second planar backing material is applied to the mixture of adhesive and absorbent that is present on the surface of one side of the first planar backing material, so producing a sandwichlike intermediate, and D) the sandwichlike intermediate is processed to the end product at a temperature of at least 90° C., a pressure of from 4 to 50 bar, and a pressing time of from 0.5 to 5 min.
