Industrial Applications of the Olefin Metathesis Reaction-- F.

Acyclic Diene Metathesis (ADMET) uses metathesis of terminal dienes to produce linear polymers and ethylene. Because ADMET is actually a variation on cross-metathesis, the process is reversible, and ethylene must be removed to drive the polymerization to completion. The polymers grow by step-growth kinetics (in contrast to the chain propagation kinetics of ROMP), so high-purity monomers are often necessary to achieve high molecular weight polymer. ADMET reactions are typically conducted highly concentrated or in neat monomer, both to help drive the polymerization equilibrium and to limit the formation of undesired cyclic oligomers by ring-closing metathesis mechanisms (“backbiting”).

It is Ring-opening metathesis polymerization.1 Chapter 1.
