Abstract:
An optical element comprising a polymeric core including a polymeric material including thioether moieties in a concentration of at least 0.05 M and at least one at least partially halogenated moiety; wherein the optical element comprisesa polymeric overclad layer; a polymeric cladding layer; and a substrate wherein the polymeric core is contiguous on at least one side with the polymeric overclad layer, and contiguous on at least one side with the polymeric cladding layer; and the polymeric cladding layer is between the polymeric core and the substrate wherein the halogenated moiety is selected from the group consisting ofâ€”(CF2)xâ€”, â€”(CF3)2Câ€”, â€”CF2Oâ€”[(CF2CF2O)m(CF2O)n]â€”CF2â€”, â€”CF(CF3)O(CF2)4O[CF(CF3)CF2O]pCF(CF3)â€”, and â€”CF2Oâ€”(CF2CF2O)mâ€”CF2â€”, wherein x is an integer between 1 and about 10;m and n designate the number of randomly distributed perfluoroethyleneoxy and perfluoromethyleneoxy backbone repeating subunits, respectively; and p designates the number of â€”CF(CF3)CF2Oâ€” backbone repeating subunits.
