Abstract:
1. A polymerizable siloxane composition crosslinkable by dehydrogenating condensation to give a product other than linear block copolyorganosiloxanes which comprises at least one ≡Si—Ar—Si≡ unit (where Ar=aromatic group), this composition comprising: —A— at least one organosiloxane monomer, oligomer and/or polymer having at least one ≡SiH reactive unit per molecule; —B— at least one organosiloxane monomer, oligomer and/or polymer having at least one ≡SiOH reactive unit per molecule; —C— at least one metal catalyst; —D— optionally at least one crosslinking inhibitor; —E— optionally at least one polyorganosiloxane (POS) resin; and —F— optionally at least one filler, wherein the catalyst —C— has formula (I) below:  in which:
