USE OF A BORON DERIVATIVE AS HEAT-ACTIVATED CATALYST FOR POLYMERISATION AND/OR CROSSLINKING OF SILICONE BY DEHYDROGENATIVE CONDENSATION

摘要

The invention concerns the use as heat-activated catalyst of at least a boron derivative of formula (I): AxB(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.
