Abstract
Norbornene monomers with fluorene group and polymer material thereof are disclosed. The norbornene monomers with fluorene group are prepared by Diels-Alder reation. The Norbomene monomers containing fluorene groups are highly active for ring-opening-metathesis polymerization (ROMP), and the molecular weight and PDI value of the obtained polymers are controllable.
