Abstract

"New"-(CH) _x and "ARA" (i.e. Additional Reducing Agent)-(CH)_x have been synthesized at room temperature. "New"-(CH)_x is formed by polymerizing acetylene on flat polymeric or glass substrates using an AlEt₃/Ti (n-BuO)₄ catalyst in silicone oil which has previously been heat-treated. Additional reducing agents may be added to the catalyst after its thermal treatment to produce "ARA"-(CH)_x. The stretch-oriented "New"-(CH)_x polymerized on glass and "ARA"-(CH)_x polymerized on polyethylene can be p-doped with I₂/CCl₄ to give conductivities of ∼50,000 and ∼75,000 S/cm respectively. Optical absorption, photoinduced infrared absorption, magnetic susceptibility and conductivity studies on selected forms of the above doped and undoped types of (CH)_x are discussed. The electronic structure of highly conducting "New"-and "ARA"-(CH)_x is observed to be essentially identical to that of conventional Shirakawa-(CH)_x.
