摘要

High trans-1,4-polybutadiene ( ～ 96% (trans)) was prepared by lanthanum naphthenate catalytic systern. The conductivity of obtained polybutadiene doped with iodine reaches about ～10-3 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-1,4-polybutadiene is fit on variable range hoping (VRH) model.
