METHOD FOR PREPARING SILICONES WITH ARYLALKYL FUNCTION(S) BY HYDROSILYLATION |
摘要 |
The invention concerns a method for preparing high purity polyorganosiloxanes with arylalkyl function(s) by: hydrosilylation of a hydrogenopolyorganosiloxane, reagent (SiH), and an aromatic monovinyl compound, reagent (Vi), with simultaneous introduction of reagent (SiH) and reagent (Vi), in a reaction medium containing an inert solvent and a hydrosilylation catalyst; then elimination of the solvent, the possible residual reagents (SiH) and (Vi), and/or hydrogenation, the hydrogenation process being optionally followed by an elimination process (or another elimination process) of the products other than polyorganosiloxanes with arylalkyl function(s). The resulting silicones with arylalkyl function(s) can be used as emollients and/or carriers in cosmetic compositions, or as solubilising agents and emollients in perfume compositions. |
