Fecha de publicación: | 2019 | Editor: | John Wiley & Sons | Citación: | Macromolecular Chemistry and Physics 220 (2019) | Resumen: | This work reports on the synthesis of a novel bifunctional norbornene dicarboximide monomer (HFDA) based on 4,4′-(hexafluoroisopropylidene)bis(p-phenyleneoxy)dianiline and its application as a cross-linking agent in the ring-opening metathesis polymerization (ROMP) with N-3-trifluoromethylphenyl-exo,endo-norbornene-5,6-dicarboximide (mCF ) employing the Grubbs 2nd generation catalyst (I) and cis-1,4-diacetoxy-2-butene as a chain transfer agent (CTA) to yield a series of soluble nonlinear highly branched chains polymers with increasing degree of cross-linking. A comparative study of gas transport in membranes based on these cross-linked polynorbornene dicarboximides is performed and the gases studied are hydrogen, oxygen, nitrogen, carbon dioxide, methane, ethylene, and propylene. It is found that cross-linking increases the gas permeability, leads to the highest separation factor reported to date for the H /C H mixture in this kind of polymers, and also enhances the CO plasticization resistance up to 14 atm upstream pressure. The chemical cross-linking approach employed in this research is an effective tool to enhance gas transport properties for dense polynorbornene dicarboximide membranes. | Versión del editor: | http://dx.doi.org/10.1002/macp.201800481 | URI: | http://hdl.handle.net/10261/185788 | DOI: | 10.1002/macp.201800481 | Identificadores: | doi: 10.1002/macp.201800481 issn: 1022-1352 e-issn: 1521-3935 |
