Stable mass polymerizable polycycloolefin compositions as 3D printing materials and a method of fabrication thereof
Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium compound, a pyridine compound, a photosensitizer and an ultra violet light blocking compound along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is exposed to suitable actinic radiation to form 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 days 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.
