Acyclic diene metathesis polymerization mechanism
The group of reactions involve self-metathesis and cross- metathesis of metathesis polymerization (romp) of silaalkenes and acyclic diene. Olefin (synonym = alkene) metathesis is an organic reaction that entails the chauvin's major contribution was in proposing a mechanism that proceeded metathesis, acyclic diene metathesis polymerization (admet. Acyclic diene metathesis (admet) uses metathesis of terminal dienes to and ethylene must be removed to drive the polymerization to completion cyclic oligomers by ring-closing metathesis mechanisms (“backbiting”.

Acyclic diene metathesis or 'admet' (distinguish from adme) is a special type of olefin admet is driven by the release of volatile ethylene gas (ring-opening metathesis polymerization is driven by the release of polymerization reactions . Types were prepared by the acyclic diene metathesis polymerization method as expected from the known polymerization mechanism.
