The m- and p- diacids have different melting points. Separate them by solidification of the vapour at low pressure? Though less easy in a lab, it would be an industrial process.

From what I read on Wiki, the diacids are made by catalytic oxidation of m- and p- xylene with oxygen. That looks affordable.

If you like polymers...

I ignore what I obtained. A C2 polyketone might be a nice ferroelectric polymer. Or a C4 one, from CO and cyclopropane?
