Claim:
A composition comprising at least 0.1 wt. % of a substrate containing at least two cycloolefin groups capable of undergoing a metathesis reaction and a metal carbene complex catalyst capable of initiating the metathesis reaction, wherein the substrate has the formula: wherein: a=1–100, c=0 or 1 and d=2–4, when d=2 or 3, Z and Q are the same or different and are each a linear, branched, cyclic or polycyclic organic residue optionally containing siloxane groups (Si—O—Si) and optionally containing heteroatoms selected from the group consisting of B, N, O, Si, P, and S, when d=4, Z is C and Q is a linear, branched, cyclic or polycyclic organic residue optionally containing siloxane groups (Si—O—Si) and optionally containing heteroatoms selected from the group consisting of B, N, O, Si, P, and S, and D is a cycloolefinic residue and is different than Q or Z; and wherein the catalyst has a structure selected from: wherein: M is ruthenium or osmium, X is an alkylidene ligand with basicity higher than that of tricyclohexylphosphine (PCy 3 ), X 1 is either PCy 3 or a neutral electron donor ligand with basicity lower than that of PCy 3 , X 2 and X 3 are either the same or different and are any anionic ligand, Z is oxygen (O) or sulfur (S), R 1 and R 2 are either the same or different and are each independently hydrogen or a substituent selected from the group consisting of C 1 –C 20 alkyl, C 2 –C 20 alkenyl, C 2 –C 20 alkynyl, aryl, C 1 –C 20 carboxylate, C 1 –C 20 alkoxy, C 2 –C 20 alkenyloxy, C 2 –C 20 alkynyloxy, aryloxy, C 2 –C 20 alkoxycarbonyl, C 1 –C 20 alkylthio, C 1 –C 20 alkylsulfonyl and C 1 –C 20 alkylsulfinyl, wherein each of the substituents is substituted or unsubstituted R 4 is a substituent selected from the group consisting of C 1 –C 20 alkyl, C 2 –C 20 alkenyl, C 2 –C 20 alkynyl, aryl, C 1 –C 20 carboxylate, C 1 –C 20 alkoxy, C 2 –C 20 alkenyloxy, C 2 –C 20 alkynyloxy, aryloxy, C 2 –C 20 alkoxycarbonyl, C 1 –C 20 alkylthio, C 1 –C 20 alkylamino, C 1 –C 20 alkylsulfonyl and C 1 –C 20 alkylsulfinyl, wherein each of the substituents is substituted or unsubstituted, and R 5 , a, b, c, and d are either the same or different and are each independently hydrogen or a substituent selected from the group consisting of C 1 –C 20 alkyl, C 2 –C 20 alkenyl, C 2 –C 20 alkynyl, aryl, C 1 –C 20 carboxylate, C 1 –C 20 alkoxy, C 2 –C 20 alkenyloxy, C 2 –C 20 alkynyloxy, aryloxy, C 2 –C 20 alkoxycarbonyl, C 1 –C 20 alkylthio, C 1 –C 20 alkylsulfonyl and C 1 –C 20 alkylsulfinyl, wherein each of the substituents is substituted or unsubstituted.
