Macromolecules 1993,26, 1633-1642 1633 acyclic diene metathesis (admet) polymerization design and synthesis of unsaturated poly(carbosi1oxane)s. 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.
