Abstract: Method for the undercoating or impregnation of natural or synthetic mineral building materials with aq. suspensions or solns. that contain 0.1-70 (10-30) wt.% at least one silicon-contg. ion exchange material of formula (I) or an oligomer thereof, w.r.t. soln. or suspension. The treatment method is a single- or multi-stage process and is opt. combined with a treatment process with organic or aq. solns. or emulsions contg. hydrolysable sil(ox)anes. Ä(YO)3Si(CH2)xÜnEX (I) x = 1-12; n = 1-3, depending on E; Y = H, Na, K, Mg, Ca or Ba; E = cation or anion exchanging gp.; and X = H or alkali(ne earth) metal ion, or OH or an anion.

Abstract: The invention relates to an organosiloxane copolycondensate comprising where R - R = in which R is C1-C10-alkylene, C5-C8-cycloalkylene or which is bonded directly to N or X, where X = NH-, N-CH3, N-C2H5, -S-, -S2-, -S3-, -S4-, 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 /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.

Abstract: The invention relates to shaped organosiloxanamine copolycondensates which contain Pd, Pt, Ru and/or Rh and optionally also promoters and/or moderators. The shaped copolycondensate, which is used as a support for metal, comprises units and units and/or Y-R units. R to R are a group in which R is an N-, X- or Y- bonded radical (for example an alkylene radical), and R is R -SiO3/2, H, CH3, C2H5 or C3H7. X is a divalent radical, such as -S-, -S2- to -S4-, -HN-CS-NH-, and Y is a monovalent radical, such as -CN-, -SCN, -SH, -S-CH3, -NH2, or -NH-(CH2)2-NH2. The support substance may have been crosslinked by means of Si-, Ti-, Zr- or Al-containing crosslinking agents. The metal-containing product has a spherical shape and is defined by means of the parameters sphere diameter, specific surface area, pore volume and bulk density. The invention furthermore relates to a preparation process, which can be carried out in a number of variants, and for the use of the metal-containing product as a catalyst for hydrogenation and oxidation reactions.
