摘要： The invention relates to a process for the preparation of .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, novel .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, a process for the polymerization of these novel .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, including the polymers, and the use of these polymers as sedimentation, flocculating, dewatering and retention aids, as additives for mineral oils, and as ion exchangers.The .alpha., .beta.-unsaturated N-substituted carboxylic acid amides are prepared by transamidation of .beta.-hydroxy or .beta.-alkoxy carboxylic acid amides with primary amines and heating of the N-substituted .beta.-hydroxy or .beta.-alkoxy carboxylic acid amides obtained as intermediate products in the vapor phase in the presence of catalysts. Primary amines are preferably used in the conversion which have no hydrogen beta to the amino group.These .alpha.,.beta.-unsaturated carboxylic acid amides may be neutralized and/or quaternized and polymerized by processes which as such are known alone or with other comonomers, and preferably acrylic or methacrylic acid derivatives such as acrylamide, to give cationic polymers. These polymers are suited for use as flocculating and sedimentation aids, as dewatering and retention aids in papermaking, as additives for mineral oils, and as ion exchangers.

摘要： The present invention relates to layered bodies consisting of at least one plastic foam and/or latex foam layer and particulate, superabsorbent polymers for the absorption of water and aqueous liquids, which bodies comprise the superabsorber on, between, or below the foamed plastic and/or latex layer in a quantitatively and/or locally predetermined and fixed areal configuration at a quantity ratio of plastic and/or latex foam to the superabsorber of 1:500 to 50:1. The plastic/latex foam may comprise fillers, pigments and/or synthetic fibers. The layered bodies have an increased absorption capacity for water and aqueous liquids; in particular under load. They are manufactured by spreading out the foam, applying the superabsorber in the predetermined quantity ratio, optionally by using a stencil, and by fixing it by means of a heat treatment. These layered bodies are used in hygienic articles, as components in natural or artificial soils, as insulating material for pipes and ducts, primarily for cables and constructional elements, as liquid-absorbing and liquid-storing component in packaging materials, and as a part in garments.
