Abstract:
1. 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 is a urethane polyether carboxylate or a urethane polyester carboxylate, functionalized with at least two cycloolefin groups, and having the formula: wherein: a=1-100, c=0 or 1 and d=2-100, 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, Z is a linear, branched, cyclic or polycyclic urethane polyether or urethane polyester 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 X X Z is oxygen (O) or sulfur (S), R R
