The conducting films of polyaniline (PANi) in the emeraldine base form, protonated (doped) with camphorsulphonic acid (CSA) and 2-acrylamido-2-metyl-1-propanesulphonic acid (AMPSA), have been studied by means of 3-cm and 8-mm waveband EPR. Two dysonian absorption lines with different linewidths were observed simultaneously. This signals, R₁ and R₂, may be related to paramagnetic centers in the amorphous (A) and crystalline (C) phases of the samples respectively. The concentration ratio of the paramagnetic centers, [R₂]/[R₁], increases with temperature and depends inversely on macroconductivity, s. As reported previously, with increasing the doping levels (x = [Acid]/[Nitrogen Site]) or temperature the films conductivity of PANi-CSA_x and PANi-AMPSA_x passes through a maximum. Moreover the PANi-AMPSA_x samples exhibit a drastic s decrease and [R₂]/[R₁] ratio increase at T > 240 K, that is caused by new phase (D) formation. Similar transition is slightly evident in the PANi-CSA_x films.
