AMMONIUM-ORGANOPOLYSILOXANE COMPOUNDS CONTAINING PLATINUM AND/OR PALLADIUM, PROCESS FOR THEIR FABRICATION, AND USE

摘要

Platinum and/or palladium containing organopolysiloxane-ammonium compounds containing units represented by the structural formula: (1) in which R1, R2 and R3 represent: R5-SiO3/2 (2) wherein R5 is an alkylene group and the free valences of oxygen are satisfied by silicon atom and additional groups of the structural formula (2), optionally with the introduction of a crosslinking agent, R4 can be R1, R2, R3 or hydrogen, alkyl, cycloalkyl or benzyl, Yx- is MeX42- or MeX62-, wherein Me is platinum or palladium and X is chlorine or bromine, and can further denote a 1 to 3 valent anion of a protonic acid capable of forming a stable salt with an amine, or the hydroxy group, and x is a number from 1 to 3. Methods for the obtaining the polymeric organosiloxane-ammonium-noble metal complexes and as well as the use thereof as catalysts for hydrosilylation and hydrogenation reactions are disclosed.
