| 摘要 |
The invention relates to a silicone composition which can be crosslinked by dehydrogenative condensation between reactive ≡SiH and ≡SiOH units and which employs a catalytic iridium complex capable of being obtained by reacting together: on the one hand, an iridium complex of formula (I): <?in-line-formulae description="In-line Formulae" end="lead"?>(IrSigmaSigma'<SUB>2</SUB>)<SUB>n </SUB><?in-line-formulae description="In-line Formulae" end="tail"?> in which: A/ n is 1 or 2 and: if n is 1, Sigma is a 3-electron radical ligand LX, if n is 2, Sigma is a 1-electron radical ligand X which behaves like a 3-electron ligand LX with the two iridium atoms, B/ Sigma', which are identical or different, preferably identical, each represent a 2-electron ligand L, on the other hand, a ligand Sigma<SUB>d </SUB>chosen from R<SUB>2</SUB>S, R<SUB>2</SUB>O, NR<SUB>3</SUB>, carbenes and organophosphorus compounds. |
