## Abstract A series of random sulfonated copolyimides containing aliphatic linkages (coโ€SPIAs) with controlled degrees of sulfonic acid groups were synthesized via a conventional twoโ€step polyimidization method. 2,4โ€Diaminobenzene sulfonic acid (2,4โ€DABS) and 1,6โ€diaminohexane (DAH) were used as s
