    摘要： A process for preparing SiC-bonded polyethersiloxanes by precious metal-catalysed addition of olefinically unsaturated polyethers onto siloxanes having SiH groups is described, wherein, prior to commencement of reaction, the siloxane having SiH groups is mixed with an olefinically unsaturated polyether and with a polyethersiloxane by stirring, and then contacted with a precious metal catalyst and optionally further additives, and the SiC bond formation reaction is conducted up to an SiH conversion, determined by gas-volumetric means, of at least 97%.

    摘要： The invention relates to a process for producing preparations including one or more mononuclear platinum complex compounds of formula (X), one or more compounds comprising carbon atoms, hydrogen atoms and at least two oxygen atoms as compound(s) from compound class II, and one or more olefinically unsaturated compound(s) selected from olefin1 and olefin2 as compound(s) from compound class III, by contacting at least one compound from each of compound classes II and III with one or more dinuclear platinum (II) compound(s) as compound(s) from compound class I. The process includes performing a first step of preparing a mixture by adding together at least two compounds selected from two different compound classes and a subsequent step of admixing the mixture obtained in the first step with one or more compounds of the still absent compound class.
