Abstract
Embodiments in accordance with the present invention encompass compositions comprising a organopalladium compound, a photoacid generator, a photosensitizer and one or more olefinic monomers which undergo vinyl addition polymerization when said composition is exposed to a suitable actinic radiation to form a substantially transparent film. The monomers employed therein have a range of optical and mechanical properties, and thus these compositions can be tailored to form films having various opto-electronic properties. Accordingly, compositions of this invention are useful in various applications, including as coatings, encapsulants, fillers, leveling agents, among others.
