High trans-l,4-polybutadiene ( −96% (trans)) was prepared by lanthanum naphthenate catalytic system. The conductivity of obtained polybutadiene doped with iodine reaches about −100 s/cm, which is 2 orders of magnitude higher than the value reported.^4,5 During the I₂-doping, the conjugated sequence was formed through double bond shifting reaction. According to the relationship between conductivity and temperature, conducting mechanism of doped high trans-l,4-polybutadiene is fit on variable range hoping (VRH) model.
