Metathesis Enables Our Next-Generation Thermoset Resins Olefin Metathesis Olefin metathesis is a chemical reaction in which a molecule with a pair of carbon-carbon double bonds, known also as olefins or hydrocarbons, come together and exchange carbon atoms with one another, forming new value-added molecules in the process.

Represented in this example, two groups of symmetrical olefins shown in pairs of two blue and two green carbon groups are transformed into two pairs of new non-symmetrical olefins shown with one blue and one green carbon group per olefin.

Low catalyst loadings, solvent-free conditions, and high yielding processes make olefin metathesis both economical and manufacturing-ready. What makes olefin metathesis cost-effective also makes it green. With fewer reaction steps, solvents, and byproducts, olefin metathesis is environmentally friendly and efficient.

Grubbs Catalyst-based olefin metathesis reactions have achieved commercial success on scales ranging from milligram to multi-ton. Broad Commercial Applications Enable Broad Industry Adoption Metathesis is broadly used by chemists in a wide range of fields, including petrochemicals, pharmaceuticals, and materials.

At Materia, we use our expertise in olefin metathesis chemistry to develop innovative and cost-effective solutions to great industrial challenges.

We use this catalyst technology in the discovery and development of a new generation of advanced materials. Common Metathesis Reactions The olefin metathesis reaction process involves the scission and reassembly of carbon-carbon double bonds to generate a completely new olefins.

While there are many variations of this reaction, the most common are: Ring Opening Metathesis Polymerization.Acyclic diene metathesis (ADMET) polymerization of 2,7-divinyl-9,9- dialkylfluorenes by ruthenium-carbene catalysts [23]. The ADMET polymerization of the octyl analogue using Ru.

Acyclic Diene Metathesis (ADMET) polymerization was established decades ago and has since developed into a robust and reliable technique. A wide range of different, new materials exhibiting unique properties has been produced via ADMET polymerization since its development.

Acyclic diene metathesis or ' ADMET ' (distinguish from ADME) is a special type of olefin metathesis used to polymerize terminal dienes to polyenes: The new double bonds formed can be in cis- or trans-configuration, the exact ratio depends on the monomer and catalyst structures.
