Synthesis of polynobornene on catalyst functionalized-MWCNTs with a 'grafting from' approach: The influence of the catalyst-MWCNT spacing

摘要

The synthesis of polynorbornene by ring opening metathesis polymerizations (ROMP) in the presence of 2nd generation Grubbs catalyst-functionalized nanotube initiators, is reported. A full characterization of Grubbs catalyst-functionalized nanotubes was performed by FTIR (Fourier Transform Infrared Spectroscopy) and TG-DTG-MS (Thermogravimetrical Analysis coupled with Mass Spectrometer), in order to quantify the amount of catalyst grafted to the nanotube surface.
