Patent

CA 2405321

The invention concerns the use as heat-activated catalyst of at least a boron derivative of formula (I): A¿x?B(R)¿y? for dehydrogenative concentration between at least a monomer, oligomer and/or polymer organosiloxane having, per molecule, at least a reactive SiH unit and at least a monomer, oligomer and/or polymer organosiloxane having, per molecule, at least a reactive SiOH unit.

La présente invention concerne l'utilisation à titre de catalyseur thermoactivable d'un moins un dérivé de bore de formule (I): (A)xB(R)y pour la déshydrogénocondensation entre, d'une part, au moins un monomère, oligomère et/ou polymère organosiloxane ayant, par molécule, au moins un motif réactif SiH et, d'autre part, au moins un monomère, oligomère et/ou polymère organosiloxane présentant, par molécule, au moins un motif réactif SiOH.
