With in the frame of this work , cross-linked polymer prepared in different percents (25:75),(50:50%) and (0:100%) (glycerol:triethanol amine) which produced polymer I, polymerII and polymerIII consequently via condensation polymerization between glycerol and triethanol amine with malice anhydride. All the polymers were identified by F.T.IR and X-Ray and the result showed that the crystillanity of the polymers as follow Polymer II> polymerIII> polymer I All the polymers were doped with CuCl2, NiCl2, FeCl2 and LiClO4 . D.C. conductivity were measured in temperature range from (298-373 K) and the experimental result showed that the electrical conductivity increase several order magnitude with increasing temperature , the efficiency of dopant increase with its electronic efficiency as evaluated from the standard reduction potential .The electrical conductivity result showed that polymer II posses the highest conductivity ,followed by polymerI and then polymer III this in the doped state while in the pure state polymerIII possess the highest conductivity , followed by polymer II and then polymer I .The energy of activation is calculated from the variation of the conductivity of the three polymers with temperature using the Arrhenius equation. The A.C. measurement is used to calculate the dielectric constant for the polymers in both pure and doped state
