Two diaminocalix[4] arene monomers were synthesized from p-tertbutylcalix[4]arene through a 4-step reaction sequence. New copoly(amic acid)s containing calix[4]arene moieties on the polymer backbone were successfully synthesized in N-methyl-2-pyrrolidone by polycondensations of 4,4ะ-oxydiphthalic a
