The present invention concerns type II photoinitiators for the free-radical crosslinking of silicone compositions, in particular acrylic silicone compositions. The present invention concerns a silicone composition C1 that can be crosslinked by exposure to radiation with a wavelength of between 300 and 450 nm, comprising: &#x2014;at least one organopolysiloxane A comprising at least one methacrylate group bonded to a silicon atom, at least one organohydrogenopolysiloxane H comprising at least two, and preferably at least three hydrogen atoms each bonded to different silicon atoms, and&#x2014;at least one free-radical photoinitiator P. The present invention also concerns the provision of a silicone composition that can be polymerized or crosslinked by free-radical process comprising a type II photoinitiator system suitable for crosslinking silicone compositions, in particular by exposure to radiation, and absorbing light radiation with a wavelength greater than 300 nm.

Organopolysiloxane composition suitable for vulcanisation into an elastomer at room temperature and new organopolysiloxane polycondensation catalysts

The invention relates to a method for preparing carbene by means of deprotonation of a precursor salt using a strong base. A purpose of the invention is to enhance the synthesis of carbenes, i.e. to simplify same, to make said synthesis more economical and to obtain a liquid or solid, stable and pure form constituting a catalytic system that is easy to store and use and that has a higher efficiency, higher yield and higher selectivity than carbene catalysts of the prior art. In order to do so, the method comprises deprotonation in a solvent including an alcohol. The invention also relates to an alcohol-containing solution and carbene, and to a solid that can be obtained from the solution, e.g. by means of sublimation.
