Our polymer substrates were synthesized and polymerized via ring opening metathesis polymerization (ROMP). These polymer substrates were transparent with high thermally and mechanical stability. Polynorbornene polymer were synthesized with various amine by monofluoromethlyphenyl group and difluoromethlyphenyl group and phenyl group. The ring opening metathesis polymerization (ROMP) of norbornene dicarboximide derivatives(MFMPhNDI, DMFPhNDI and PhNDI) bearing phenyl groups was carried out with well-defined vinylidene ruthenium catalyst. This catalyst is highly active for the polymerization of norbornene dicarboximide derivatives. All of the prepared polymers have high average-transmittance from 400 to 800 nm Their glass transition temperatures were detected at temperatures over 200℃.The another properties of polymers were investigated by GPC, TGA, WXRD, AFM, UV-Vis, FT-IR, AFM, etc. |
