We present the Li NMR spin-lattice relaxation and line shape investigations perfomed at different concentrations of salt and temperatures. Addditional informations of DC electrical conductivity and thermal analysis (DSC) were also obtained. The results show that the increase of ion concentration in the polymer affects strongly the relaxation processes. Line shape analysis reveals that the dipolar magnetic interactions are predominant.  aAnálise  aTermica1 aBONAGAMBA, T. J.1 aPANEPUCCI, H.1 aVALENCIANO, G. R.1 aMATTOSO, L. H.
