Kind Code:
B2
Abstract:
The invention relates to an organosiloxane copolycondensate comprising where R<1> - R<5> = in which R<6> is C1-C10-alkylene, C5-C8-cycloalkylene or which is bonded directly to N or X, where X = <2bL>NH-, <2bL>N-CH3, <2bL>N-C2H5, -S-, -S2-, -S3-, -S4-, <2bL>P-C6H5, where R" is H or C1-C5-alkyl, which has optionally been crosslinked by means of Si-, Ti-, Zr- and/or Al-containing crosslinking agents, in the form of spherical particles having a diameter of from 0.01 to 3.0 mm, a specific surface area of from 0 to 1000 m<2>/g, a specific pore volume of from 0 to 6.0 ml/g and a bulk density of from 50 to 1000 g/l. The invention furthermore relates to various preparation processes for the shaped copolycondensates, and to the use of certain compositions in each case for removing metals from solutions or for adsorption of gaseous organic compounds and/or steam.
