DOI: 10.1002/app.44534
Abstract: A novel polysulfone was easily synthesized by alternating copolymerization of norbornene with sulfur dioxide (SO2) via free radical copolymerization and coordination copolymerization. Compared with other olefin derivatives, norbornene is a cyclic olefin having a larger… read more here.

DOI: 10.1002/marc.202200902
Abstract: The segmental dynamics of the side chains of poly(norbornene)-g-poly(propylene oxide) (PNB-g-PPO) bottlebrush polymer in comparison to PPO is studied by quasi-elastic neutron scattering. Having experimental time and length scale information simultaneously allows to extract spatial… read more here.

DOI: 10.1039/d1py00665g
Abstract: Poly(norbornene)s carrying platinum–acetylide complex moieties change their photoluminescence colors in response to oxygen. The polymers serve as excellent sensitizers of TTA–UC with 9,10-diphenylanthracene. read more here.

DOI: 10.3390/md15070223
Abstract: ROMP is an effective method for preparing functional polymers due to its having characteristics of “living” polymerization and rapid development of catalysts. In the present work, poly(norbornene-methylamine), a mimic of chitosan, was synthesized via ROMP… read more here.
