| abstract |
The invention relates to a process for the addition reaction between compounds containing hydrogen bonded to silicon and compounds comprising aliphatic unsaturation, as well as to compositions which can be used in this process. Said method is activated by actinic radiation and is carried out in the presence of a platinum complex having a single diolefin group, exhibiting an eta bond with the platinum atom, and two aryl groups exhibiting a sigma bond with the atom of platinum, as well as a free radical photoinitiator which is capable of absorbing actinic radiation, so that the hydrosilation reaction is triggered by exposure to actinic radiation. The invention also relates to compositions for use in said method. |
