Abstract: Embodiments in accordance with the present invention encompass compositions encompassing a latent organo-ruthenium catalyst, an organo-ruthenium compound and a pyridine compound along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is heated to a temperature from 80° C. to 150° C. or higher to form a substantially transparent film. Alternatively the compositions of this invention also undergo polymerization when subjected to suitable radiation. The monomers employed therein have a range of refractive index from 1.4 to 1.6 and thus these compositions can be tailored to form transparent films of varied refractive indices. The compositions of this invention further comprises inorganic nanoparticles which form transparent films and further increases the refractive indices of the compositions. Accordingly, compositions of this invention are useful in various opto-electronic applications, including as coatings, encapsulants, fillers, leveling agents, among others.

Abstract: The invention relates to impact-modified, thermoplastic compositions, where the measured refractive index difference between the impact modifier particles and the matrix composition is greater than 0.008 units, yet a blend of the impact modifier particles in the matrix produces a transparent composition. The impact modifier particles are preferably impact modifier composite particles, being intimately blended with one or more polymeric process aids or dispersing aids. The polymeric process aids are physically or chemically attached to the impact modifier particles, forming composite particles that allow for facile powder isolation. The impact modifier composite particles provide improved physical, chemical, and/or rheological properties to the thermoplastic composition. Preferably the impact modifier particles of the invention are core-shell impact modifiers.
