Abstract
Olefin metathesis polymerization has commanded great attention as a versatile method
for preparing macromolecular materials with advanced architectures and functions in
academia and industry. This Account summarizes our endeavors directed towards the
preparation of various functional polymers by using olefin metathesis polymerization
strategies in particular acyclic diene metathesis (ADMET) polymerization and ring-opening
metathesis polymerization (ROMP), during the last ten years. In addition, the merits
and limitations of ADMET polymerization and ROMP techniques are also demonstrated
and compared. Notably, this Account highlights our recently developed sequence-controlled
ROMP strategy for production of precision polymers in a regio-/stereoselective manner,
the rollercoaster journey for the evolution of a macrobicyclic olefin system containing
a sacrificial silyloxide bridge is described in detail.
