Abstract
The present invention relates to initiators of cationic polymerization and/or crosslinking, under photochemical and/or thermal activation and/or activation by a beam of electrons, of monomers and/or polymers containing organofunctional groups. These initiators give good performance with the majority of monomers/polymers, including in particular functional polyorganosiloxanes, which are crosslinkable cationically and under UV. The subject of the invention is also compositions based on at least one cationically crosslinkable polyorganosiloxane and on at least one initiator, as defined above. Application: paper anti-adhesion.
