SILICONE COMPOSITION POLYMERISABLE AND/OR CROSSLINKABLE BY CATIONIC PROCESS, UNDER THERMAL ACTIVATION AND BY MEANS OF A LEWIS ADDUCT INITIATOR

摘要

The invention concerns a composition for polymerisation and/or crosslinking by cationic process under thermal activation, involving monomers, oligomers and/or polymers of the organosiloxane type and bearing reactive functions. Said composition further comprises as initiator thermally stable at room temperature and capable of being activated between 50 and 100 DEG C, a Lewis adduct consisting of a Lewis acid of the type of boron halogenated aromatic derivative (C>65<)>3
