Title (EN) RADIATION ACTIVATED HYDROSILATION REACTION
(FR) REACTION D'HYDROSILATION ACTIVEE PAR EXPOSITION A UN RAYONNEMENT
Abstract:
(EN) Numerous patents teach the use of various complexes of cobalt, rhodium, nickel, palladium, or platinum as catalysts for accelerating the thermally-activated addition reaction (hydrosilation) between a compound containing silicon-bonded hydrogen and a compound containing aliphatic unsaturation. Although platinum complexes and many others are useful as catalysts in processes for accelerating the thermally-activated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for promoting the ultraviolet or visible radiation-activated addition reaction between these compounds are much less common. This invention provides a process for the addition reaction of compounds containing silicon-bonded hydrogen with compounds containing aliphatic unsaturation and compositions suitable for said process. The process is activated by actinic radiation and is conducted in the presence of a platinum complex having one diolefin group that is $i(eta)-bonded to the platinum atom and two aryl groups that are $i(sigma)-bonded to the platinum atom and a sensitizer that is capable of absorbing actinic radiation and is capable of transferring energy to said platinum complex such that the hydrosilation reaction is initiated upon exposure to actinic radiation. The invention also provides compositions for use in the aformentioned process.
(FR) Un grand nombre de brevets prônent l'utilisation de divers complexes de cobalt, de rhodium, de nickel, de palladium ou de platine comme catalyseurs pour accélérer la réaction d'addition thermo-activée (hydrosilation) entre un composé contenant de l'hydrogène lié au silicium et un composé comportant une insaturation aliphatique. Bien que les complexes de platine et un grand nombre d'autres complexes soient utiles comme catalyseurs dans des procédés qui accélèrent la réaction d'addition thermo-activée entre des composés contenant de l'hydrogène lié au silicium et des composés comportant une insaturation aliphatique, les procédés qui favorisent la réaction d'addition activée par les ultraviolets ou les rayonnements visibles entre ces composés sont beaucoup moins répandus. La présente invention propose un procédé qui permet la réaction d'addition de composés contenant de l'hydrogène lié à du silicium avec des composés comportant une insaturation aliphatique, ainsi que des compositions utilisables dans ce procédé. Ledit procédé est activé par rayonnement actinique et il s'effectue en présence d'un complexe de platine ayant un seul groupe dioléfine, présentant une liaison $i(éta) avec l'atome de platine, et deux groupes aryle présentant une liaison $i(sigma) avec l'atome de platine, ainsi qu'un sensibilisateur qui est capable d'absorber le rayonnement actinique et de transférer l'énergie vers le complexe de platine, pour que la réaction d'hydrosilation se déclenche par exposition au rayonnement actinique. L'invention se rapporte également à des compositions à utiliser dans ledit procédé.
