The present invention relates to particles obtainable by polymerization of a siloxane containing at least one (meth) acrylate group of the formula (I) -OC (O) -CR = CH 2 (I) with R = -H or -CH 3 , which are characterized in that the siloxane has an average molar ratio of groups of the formula (I) to Si atoms of less than 0.1, a process comprising the steps: a) generating an emulsion of an aqueous phase and an organic phase, the organic phase having at least one siloxane having at least one (meth) acrylate group of the formula (I), with the addition of at least one solid-state emulsifier and mixing of the two phases, wherein the Organic phase forms the inner phase of the emulsion, and b) polymerizing the inner phase in the presence of a radical initiator, which is more soluble in the organic phase than in the aqueous phase, which is characterized in that the siloxane used an average molar ratio of groups of the formula (I) to Si atoms of less than 0.1, correspondingly prepared particles and the use of the particles. |
