Title (EN) RADIATION ACTIVATED HYDROSILATION REACTION
(FR) REACTION D'HYDROSILATION ACTIVEE PAR EXPOSITION A UN RAYONNEMENT
Abstract:
(EN) This invention discloses a process for the addition reaction of compounds containing silicon-bonded hydrogen to 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 free-radical photoinitiator that is capable of absorbing actinic radiation such that the hydrosilation reaction is initiated upon exposure to actinic radiation. The invention also provides compositions for use in the aforementioned process.
(FR) L'invention se rapporte à un procédé permettant la réaction d'addition entre des composés contenant de l'hydrogène lié à du silicium et des composés comportant une insaturation aliphatique, ainsi qu'à 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, présenant 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 photoinitiateur à radicaux libres qui est capable d'absorber le rayonnement actinique, 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.
