摘要：

Five different poly(2-methylaniline) salts were prepared by chemical polymerization of 2-methylaniline using different protonic acids. The salts were converted into their bases by using aqueous NH4OH. EPR spectra were recorded for the solid samples of poly(2-methylaniline) salts and their bases in the temperature range 40-200-degrees-C at intervals of 40-degrees-C. PMA salts and their bases consist of highly mobile radical cations or polarons. The salts show a thermally activated paramagnetism, i.e., polarons are antiferromagnetically coupled to each other, while the bases show temperature-independent or Pauli-type paramagnetism.
