Patent ID: 7214475

Claim:
A method of forming an optical film, said method comprising: (a) providing a blend of monomer A and monomer B, said monomer A comprising a polycyclic or monocyclic perfluorovinyl compound comprising at least one structural unit selected from the group consisting of formula I and formula II wherein M is independently at each occurrence a metal selected from group 14 of the periodic table of the elements, R is independently at each occurrence a bond, a hydrogen, an aliphatic group, a cycloaliphatic group, or an aromatic group; said polycyclic or monocyclic compound comprising at least two perfluorovinyl groups, said monomer B being an organic compound comprising at least two CF 2 ═CF— units; (b) mixing said blend with a photo-initiator and a photo-curable monomer C, wherein said photo-curable monomer C comprises at least one of an acrylate, an epoxy, a polyimide, a silicone, a vinyl compound, a carbonate, and a diene, to yield a mixed blend; (c) partially polymerizing at least one of the blend and the mixed blend; (d) depositing said mixed blend on a substrate to form a film; (e) selectively exposing said film to radiation to at least partially polymerize monomer C; and (f) curing said film.
