NORBORNENE CROSS-LINKED POLYMER AND METHOD FOR PRODUCING SAME
The present invention relates to a norbornene-based crosslinked polymer containing at least one member selected from the group consisting of dicyclopentadiene-based monomer units, tetracyclododecene-based monomer units, and tricyclopentadiene-based monomer units in an amount of 50% by mass or more, wherein the norbornene-based crosslinked polymer has a glass transition temperature of 240 C. or higher. Further, the present invention relates to a method for producing a norbomene-based crosslinked polymer as defined above, including step (1): heating a blend containing at least one member of the above monomer components, and a metathesis polymerization catalyst to a temperature lower than a deactivation temperature of the metathesis polymerization catalyst to carry out a primary curing; and step (2): heating a cured product obtained in the step (1) to a temperature equal to or higher than the deactivation temperature of the above metathesis polymerization catalyst to carry out a secondary curing.
Water soluble homogeneous catalysts that are recoverable by phase selectivity and host-guest interactions
This describes homogeneous catalysts that are recoverable from solution by being phase selective and through host-guest interactions. An example of a method includes separating a water soluble N-heterocyclic carbene homogeneous catalyst from a solution by: (a) forming a host-guest compound between the catalyst and an inclusion compound in the solution; and (b) isolating the host-guest compound from the solution.

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.
