Abstract: Silicone urethane (meth)acrylates can have at least three (meth)acrylate groups and not more urethane groups than (meth)acrylate groups. A method for preparing the silicone urethane (meth)acrylates involves reacting at least one hydroxy functional silicone (meth)acrylate with at least one isocyanate functional urethane (meth)acrylate. Compositions can contain the silicone urethane (meth)acrylates, and are useful for the production of release coatings, protective films, and protective coatings; and for the manufacturing of 3D printed objects by stereolithography.

Abstract: Mixture compositions contain A) crosslinked organopolysiloxanes having organopolysiloxane units linked by a building block containing polyether groups, and B) crosslinked organopolysiloxanes having organopolysiloxane units bridged by a bridging siloxane. The mixture compositions are useful, for example, as an emulsifier, for stabilizing formulations, and for dispersion of solid pigments.

Abstract: The invention relates to functionalized polymers, a process for producing functionalized polymers and the use of functionalized polymers, especially in the field of personal care.

Abstract: A functionalized polymer contains monomeric units of general formula (I) In general formula (I), R1 is selected from alkyl radicals and alkenyl radicals, which may be branched or straight chained, and unsubstituted or substituted: and R2 is selected from H and methyl. The monomeric units of general formula (I) make up for at least 90 wt.-% of the total weight of the polymer. The polymer has a polydispersity index PDI of 4.5 to 20. A process for can be used producing the functionalized polymers. The functionalized polymers are useful, especially in the field of personal care.
