Acetylene polymerized by a heat aged mixture of Ti(OBu)₄^-AlEt₃ in various solvents (alkane and aromatic hydrocarbon)yields a high performance polyacetylene film (HPPA).Being doped with iodine, the films showed an electrical conductivity of 10³ S/cm at room temperature. The value was over 10⁴ S/cm after stretching of the film. The HPPA films were high compact and stable in air and composed of relatively ordered piling up of fibrils.Its apparent density and permeability of N₂ were 0.80g/cm³ and 3.2×10¹¹ Jcm³(STP)/cm²·s·cmHg,respectively. The results of IR, TEM and X-ray diffraction indicated that the films were high crystalline and had 65-85% of cis-PA and 20-100 nm of fibre diameter.
