  • Patent number: 7060769
    Abstract: A method of controlled curing by a metathesis reaction upon mixing its components, the method including the step of mixing an olefin-containing substrate, a metathesis catalyst, and a reaction control agent. The metathesis catalyst is a ruthenium or osmium carbene complex catalyst, such as one containing an alkylidene ligand with basicity higher than that of tricyclohexylphosphine (PCy3) and a neutral electron donor ligand with a basicity lower than that of PCy3, whereby the catalyst initiates the metathesis reaction of the composition upon mixing with the substrate. The reaction control agent is effective to slow the progress of the metathesis reaction and prevent its completion in the absence of an elevated temperature. The control agent may be a hydrocarbon containing carbon-carbon double bonds and/or triple bonds, or maybe a modified hydrocarbon with one or more Group 14 or 15 atoms.

  • Patent number: 7060770
    Abstract: 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. The metathesis catalyst is a ruthenium or osmium curbene complex catalyst, such as one containing an alkylidene ligand with basicity higher than that of tricyclohexylphosphine (PCy3) and a neutral electron donor ligand with a basicity lower than that of PCy3, whereby the catalyst initiates the metathesis reaction of the composition upon mixing with the substrate. The reaction control agent is an organic compound that contains 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.
