The temperature dependence of resistivity and magnetoconductivity of iodine doped helical polyacetylene was investigated to review the effect of intrafibril and interfibrillar interaction in the polyacetylene system. The negative component of magnetoconductivity was inversely proportional to temperature in the low magnetic field region. The positive magnetoconductivity depicted a linear dependence on the magnetic field. Charge conduction depended on the strength of interfibrillar interactions since the fibers in R-polyacetylene were more tightly twisted than in S-polyacetylene.
