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.

Abstract: A monomer capable forming a polymer through ring-opening metathesis polymerization and capable of depolymerization thereafter through ring-closing metathesis, wherein the monomer comprises a cycloalkene having a fused ring attached thereto to form a cycloalkene-fused ring monomer, wherein the fused ring decreases the ring strain energy of the cycloalkene to a lower ring strain energy state of 5.3 kcal/mol or lower as compared to the same cycloalkene without the fused ring having a ring strain energy above 5.3 kcal/mol and wherein the cycloalkene-fused ring monomer is capable of isomerization into a higher ring strain energy state before polymerization and method of synthesizing the monomer. The monomer is further capable of forming chemically recyclable to monomers block copolymers.
