    Abstract: Embodiments in accordance with the present invention encompass compositions encompassing a latent catalyst and a thermal or photoactivator along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is heated to a temperature from 50° C. to 100° 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: Embodiments in accordance with the present invention encompass compositions containing a latent catalyst and a compound capable of generating a Bronsted acid with a counterion capable of coordinating and activating the latent catalyst along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said composition is exposed to a suitable radiation to form a three-dimensional (3D) object. The catalyst system employed therein can be sensitive to oxygen and thus inhibits polymerization in ambient atmospheric conditions. The three-dimensional objects made by this process exhibits improved mechanical properties, particularly, high distortion temperature, impact strength, elongation to break, among others. Accordingly, compositions of this invention are useful as 3D inkjet materials for forming high impact strength objects of various sizes with microscale features lower than 100 microns, among various other uses.

    Abstract: Embodiments in accordance with the present invention encompass self-imagable polymer compositions containing a variety of photobase generators which are useful for forming films that can be patterned to create structures for microelectronic devices, microelectronic packaging, microelectromechanical systems, optoelectronic devices and displays. The compositions of this invention can be tailored to form positive tone or negative tone images depending upon the intended application in aqueous developable medium. The images formed therefrom exhibit improved properties including low wafer stress and better thermo-mechanical properties, among other property enhancements.
