Abstract
Embodiments in accordance with the present invention encompass compositions encompassing components A and B which respectively contain a procatalyst and an activator along with one or more monomers which undergo vinyl addition polymerization when both components are mixed together to form a substantially transparent film. The monomers employed therein have a range of refractive index from 1.4 to 1.8 and thus these compositions can be tailored to form transparent films of varied refractive indices. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.
