ABSTRACT:
This invention relates to formed, polymeric complexes of metals of the eighth subgroup of the periodic system with ligands of an organosiloxane copolycondensate optionally cross-linked by means of cross-linking agents containing Si, Ti, Zr and/or Al, in the form of statistical, block or mixed copolycondensates. The ratio between the number of moles of phosphine units and the number of moles of bound metal atoms is 1:1 to 1000 to 1 and the ratio between the amine units and the phosphine is preferably 5:95 to 95:5 mole %. The polymeric complex compounds are present macroscopically as spherical particles with a diameter in the range of 0.01 to 3.0 mm, a BET surface of greater than 0 to 1000 m.sup.2 /g, a specific pore volume of 0.01 to 6.5 ml/g and a bulk density of 50 to 1000 g/l. The invention also includes several methods of preparing the complexes with post-treatment stages and the use of the polymeric metal complexes as catalysts in organic chemistry.
