We have prepared polyacetylene (ν-(CH)_x) yielding a conductivity of more than 10^5 S/cm, by making some modifications on Naarmann et al.'s method. Structural analyses of this polymer were carried out by use of various analysis techniques such as SEM, IR and resonance Raman spectroscopy to characterize ν-(CH)_x. No distinct differences in structure between conventional polyacetylene and ν-(CH)_x were observed except for morphology and specific gravity. Upon iodine doping, conductivity increases stepwisely, which may suggest the formation of a staging structure and / or the transformation to metallic phase. However, in the temperature dependence of conductivity, we could not find any differences which distinguish the metallic ν-(CH)_x from conventional polyacetylene.
