    IPC: C08J9/00

    Abstract: Use of moldings whose length width height dimensions are always in the range from 1 mm to 3 cm, at least one dimension being greater than 5.5 mm, produced by treatment of (a) open-cell foam whose density is in the range from 5 to 500 kg/m3 and whose average pore diameter is in the range from 1 mum to 1 mm (b) with an aqueous formulation of at least one compound having at least one hemiaminal or aminal group per molecule or at least one copolymer containing at least one copolymerized comonomer which contains OH groups or which contains beta-dicarbonyl groups, or which contains epoxy groups, (c) and a shaping step, as dust binders in vacuum cleaners.

    IPC: C08J9/00

    Abstract: The invention relates to the use of molded bodies as dust-binding means i n vacuum cleaners. The molded bodies according to the invention have length/ width/height dimensions ranging from 1 mm to 3 cm, at least one dimension be ing larger than 5.5 mm, and are produced by treating (a) an open-cell foam m aterial having a density ranging from 5 to 500 kg/m3 and a mean pore diamete r ranging from 1 .mu.m to 1 mm (b) with an aqueous formulation of at least o ne compound having at least one hemiaminal group or aminal group per molecul e or at least one copolymer which contains at least one OH group- or .beta.- dicarbonyl group- or epoxy group-containing comonomer polymerized into it, ( c) and a shaping step.
