Definitions
- the field of the invention is that of silicones, namely (poly) organosiloxanes, functionalized in particular by unsaturated carboxylic acid ester groups such as (meth) acrylate functions.
- (meth) acrylates corresponds to the methacrylate or acrylate ester.
- the functionalization of the polyorganosiloxanes by (meth) acrylate groups is a reaction which arouses great interest because it not only gives access to other functionalities by chemical post-treatment, but also makes it possible to obtain polyorganosiloxanes having faster crosslinking than commercially available vinyl organopolysiloxanes.
- (Meth) acrylates are able to react rapidly together, by radical means under actinic and / or thermal activation, according to a polyaddition polymerization mechanism.
- acrylate or methacrylate functional polyorganosiloxanes are generally in the form of polydiorganosiloxane oils and may be formulated alone or in combination with unsaturated monomers or polymers, to be subsequently crosslinked under UV radiation, for example.
- patent application FR-A-2,377,430 describes acrylate silicones obtained by addition of hydroxyalkyl acrylate grafts on silicones with chlorosiloxane functions.
- These acrylate and / or methacrylate functional polyorganosiloxanes thus comprise functional grafts connected to the silicone chain by means of bonds Si-O.

- the problem with this hydrosilylation modified triacrylate (trimethylolpropane type or propyleneoxide triacrylate "ARONIX M-310 ®"), according to US-A-5,981,679 is that it generates 50% of polyorganosiloxanes bearing functionalised grafts acrylates and linked to the silicone chain by stable SiC bonds, but also 50% silicone-bound polyacrylate grafts by an easily hydrolysable Si-OC bridge.
- the direct hydrosilylation of polyacrylates by polyorganosiloxanes with an SiH unit in and / or at the end of the chain may involve, for example, 1,6-hexanedioldiacrylate, trimethylolpropane triacrylate, triethylene glycol diacrylate or neopentylglycol. diacrylate, or else tripropylene glycol-diacrylate and finally bisphenol ethoxylated diacrylate.
- French Patent Application FR-A-2,634,769 describes a thioalkyl acrylate-functional diorganopolysiloxane obtained by reacting a vinyl-containing polyorganosiloxane, for example an ⁇ , ⁇ -dimethylvinylsiloxy linear polydimethylsiloxane, with a mercaptoalkanol which reacts with the vinyl functional groups via thiol groups, so as to produce an ⁇ , ⁇ -thioalkylhydroxylated polydimethylsiloxane.

This polyorganosiloxane is then reacted with a derivative of acrylic or methacrylic acid for introducing an acrylate group.
- These acrylate silicones result from the hydrosilylation of allyl glycidyl ether (AGE) and a vinylcyclohexene epoxide (VCMX) in the presence of a platinum catalyst on an SiH functional polyorganosiloxane.
