| 5-[2-(4-Vinyl-phenyl)-ethyl]-bicyclo[2.2.1]hept-2-ene (NSt) was successfully synthesized via a simple Grignard reaction, purified and characterized by EI-MS, NMR, and IR spectroscopies. We demonstrated that by anionic or free radical polymerization of NSt, linear polystyrene containing pendant norbornene functionality was produced in a controlled manner. In addition, by ring-opening metathesis polymerization (ROMP) of NSt, a highly branched polymer with 4-vinyl phenyl pendant groups was formed. Furthermore, norbornene-functionalized diblock copolymers were prepared through reversible fragmentation-addition chain transfer (RAFT) polymerization of NSt, using an appropriate polymeric chain transfer agent (CTA). All polymers were characterized by SEC and 1H-NMR spectroscopy. |
