US 2023/0167256 A1 · DUAL UV BLOCKERS CONTAINING STABLE PHOTOACTIVE MASS POLYMERIZABLE POLYCYCLOOLEFIN COMPOSITIONS AS OPTICAL MATERIALS

Abstract

Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound, a photosensitizer, one or more monomers which undergo ring open metathesis polymerization (ROMP) and at least two distinct types of UV blockers, where when said composition is exposed to suitable actinic radiation forms a substantially transparent film or a three dimensional object. Surprisingly, the compositions are very stable at ambient conditions to temperatures up to 80° C. for several weeks and undergo mass polymerization only when subjected to actinic radiation under inert atmosphere such as for example a blanket of nitrogen. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as 3D printing materials, coatings, encapsulants, fillers, leveling agents, among others.
