Abstract:
An optical article comprising:a three-dimensional cross-linked polymer matrix, and one or more polymers formed from one or more photoactive monomers, wherein the matrix was formed by a polymerization reaction selected from cationic epoxy polymerization, cationic vinyl ether polymerization, cationic alkenyl ether polymerization, cationic allene ether polymerization, cationic ketene acetal polymerization, epoxy-amine step polymerization, epoxy-mercaptan step polymerization, unsaturated ester-amine step polymerization, unsaturated ester-mercaptan step polymerization, vinyl-silicon hydride step polymerization, isocyanate-hydroxyl step polymerization, and isocyanate-amine step polymerization, wherein at least one of the photoactive monomers comprised a moiety, other than the monomer functional group, that is substantially absent from the polymer matrix, wherein the polymer matrix and the one or more polymers formed from the one or more photoactive monomers are compatible, wherein the matrix has a thickness greater than 200 &mgr;m, and wherein the polymer matrix was formed, in the presence of the one or more photoactive. monomers, by a polymerization reaction independent from a reaction by which the one or more photoactive monomers were polymerized.
