Abstract:
A composition consisting essentially of:one or more density modulators dispersed in a polycyclic olefin resin matrix prepared by the metathesis of an olefin monomer using a ruthenium or osmium metal carbene catalyst of the formula: â€ƒwherein: M is ruthenium or osmium; X and X1 are either the same or different and are any anionic ligand; L and L1 are either the same or different and are any neutral electron donor; R and R1 are either the same or different and are each independently hydrogen or a substituent selected from the group consisting of C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl and C1-C20 alkylsulfinyl, wherein each of the substituents is unsubstituied or substituted with one or more substituted or unsubstituted moieties selected from the group consisting of C1-C20 alkyl, C1-C10 alkoxy, and aryl.
