In the last two decades, the use of engineering polymer membranes for gas
separation has received a widespread attention. Currently, commercially available
polymers for this purpose are glassy polymers, such as polysulfones, cellulose
acetates and polyimides which offer high common solvent solubility, have good
thermal and mechanical properties as well as excellent intrinsic CO 2 /CH 4 separation
properties. Despite these attractive features, polymeric membrane performance is
limited and challenged by plasticization. To enhance plasticization resistance,
thermally and chemically crosslinked polymeric membranes have been developed
for the separation of the more condensable gases.
Several studies have focused on norbornene since this monomer can be easily
modified, thus facilitating the way to prepare a homologous functionalized series of
norbornene derivatives that may be subjected to different polymerization reactions
yielding materials whose structures and properties depend on the kind of catalyst
employed. In this regard, the ring-opening metathesis polymerization (ROMP) is a
unique tool for synthesizing macromolecules that cannot be prepared by
conventional methods. Based on the latter, in this work we report on the synthesis
of new difunctionalized norbornene monomers and their use as crosslinking agents
in the ROMP with norbornene dicarboximides to yield a series of soluble polymers
with increasing degree of crosslinking. In general, membranes prepared these
crosslinked polynorbornenes exhibit rather good gas transport properties and
enhanced plasticization resistance which make them suitable materials for their
potential use in packaging and gas separation processes.
