Two new aliphatic diamine monomers, one containing cyclohexane moiety and the other containing both cyclohexane and trifluoromethyl moieties, were synthesized. Two series of semi-aromatic polyimides (PIs) derived from the two diamines were prepared by one-step solution polycondensation using m-cresol as solvent.
