The invention relates to a method for producing siloxanes that have glycerin modifications and, at the same time, hydrophobic substituents. The invention further relates to a siloxane that has glycerin modifications and also hydrophobic side chains, wherein at least some of the glycerin modifications bear ketal groups, and to the use of said new siloxanes.

Method for producing siloxanes containing glycerin substituents

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.
