Synthesis and Properties of Hydrogenated Metathesis Oligonorbornene

Metathesis oligomerization of norbornene in the presence of the first-generation Grubbs catalyst and ethylene used as a chain transfer agent yielded an oligomeric product, which was then hydrogenated over a palladium catalyst. After oligomerization and modification, the yield of the products was over 80 and 90%, respectively. The structure of the oligomers was confirmed by 1H and 13C NMR spectroscopy. Thermal and rheological properties of the obtained oligomer have been studied in detail.
