New polyimide containing cvalix[4]arene moieties on the polymer backbone was successfully synthesized in N-methyl-2-pyrrolidone(NMP) by polycondensations of 3,3, 4, 4- oxydiphthalic anhydride (ODPA) with the diaminocalix[4]arene monomer using 3,3-dimethyl-4, 4-diaminodiphenylmethane(DADPM) as a third comononmer.The polyimide prepared is soluble in common solvents, such as NMP, DMAc, DMF and chloroform. The polyimide films obtained have excellent thermal stability and mechanical property. At the same time, the liquid membrane transport of potassimn ions by the new polyimide was investigated, which testified that compared to ODPA-DADPM polyimide, the polyimide containing calix[4] arenes has the transport ability to metal ions in regard to bulky, cone-like calix [4] arene moieties.
