The present invention relates to organosiloxane-amine copolycondensates crosslinked, when required, by means of Si-,Ti-,Zr-and/or Al-containing crosslinking agents and comprising units (see fig.I) and X - R4 wherein R1 - R4 = R5 - (see fig.II) wherein R5 represents alkylene directly linked to N and R respectively and containing C1 - C10, cycloalkylene with C5 - C10 or (see fig.III) and (see fig,IV) X = -NH2, -NH-(CH2)2-NH2. -N(CH3)2, -N(C2H5)2 -NH-(CH2)2-NH-(CH2)2-NH2, -Cl, -Br, -J, -SH, -P(C6H5)2, (see fig.V), (see fig.VI), (see fig.VII) (see fig.VIII), (see fig.IX) wherein R" represents H or alkyl with C1 - C5, in the form of globular particles having a diameter of 0.1 to 3mm, a specific surface area of 0 to 1000 m2/g, a specific pore volume of 0 to 6.0 ml/g and a powder density of 50 to 1000 g/litre. The present invention also relates to several processes of producing the formed copolycondensates of various specific compositions for the removal of metals from solutions and for the adsorption of gaseous organic compounds and/or of water vapour.
