PROBLEM TO BE SOLVED: To provide a composition curable by a metathesis reaction upon mixing its components and comprising an olefin-containing substrate, a metathesis catalyst, and a reaction control agent for slowing the progress of the metathesis reaction. SOLUTION: The metathesis catalyst is a ruthenium or osmium carbene complex catalyst having high activity and good stability in air. The catalyst is free of phosphine ligands. The reaction control agent is an organic compound containing carbon-carbon double and/or triple bonds and one or more group 14 atoms and is present in an amount effective to slow the progress of the metathesis reaction. Alternatively, the olefin-containing substrate may contain one or more oligomers or polymers having a >20 wt.% linear siloxane (Si-O-Si) skeleton tethered and/or end-capped with functional olefin groups, such as cycloalkenyl group.
