Abstract: The formed sulphonate and SH gp.-contg. organo-polysiloxanes (OFP) contain units of formula (I) and (III): ÄO3/2SiR1SO3ÜxMx+ (I) O3/2SiR2SH (III) where R1 = 1-12 C alkylene, 5-8 C cycloalkylene or a gp. of formula -(CH2)n-Cy-(CH2)m- or -(CH2)n-Ph-(CH2)m- (II); where n and m = 0-6; Cy = cyclohexylene; Ph = phenylene; M = H, NH4 or a metal ion with a valency of 1-4; R2 = R1; the free valencies of the O atoms attached to Si are taken up by the Si atoms in other gps. (I) and/or (II) and/or by the metal atom-oxygen gps. in crosslinking bridging gps. of formula SiO4/2 (IV) and opt. R''SiO3/2, R'SiO3/2, AlO3/2, R'AlO2/2, TiO4/2, R'TiO3/2 (V), in which R' = Me or Et; R" = Ph or 2-12 C alkyl. The ratio of gps. (I):(III) is 10:1-1:10, the ratio of gps. (I):(IV) is 1:3-1:20 and the ratio of gps. (IV):(V) is 1:0-1:0.5. Also claimed is a process for the prodn. of OFP.

Abstract: The invention relates to shaped polymeric complexes of metals from sub-group 8 of the Periodic Table with ligands of an organosiloxane copolycondensate (random, block or mixed) which is optionally crosslinked by means of Si-, Ti-, Zr- and/or Al-containing crosslinking agents. This copolycondensate comprises units … … and … …… where R - R are … …… in which R is directly P- or N-bonded C1-C10-alkylene, C5-C8-cycloalkylene or … …. The ratio between the number of moles of units (II) and the number of moles of bonded metal atoms is from 1:1 to 1000:1, and the ratio between the units (I) and (II) is preferably from 5:95 to 95:5 mol%. … The polymeric complex compounds are in macroscopic form as spherical particles having a diameter of from 0.01 to 3.0 mm, a BET surface area of from >0 to 1000 m /g, a specific pore volume of from 0.01 to 6.5 ml/g and a bulk density of from 50 to 1000 g/l. … The invention also relates to a number of preparation processes for the substances according to the invention with specific aftertreatment steps, and the use of the polymeric metal complexes as catalysts in organic chemistry.
