Abstract
“New”-(CH)
x and “ARA” (i.e.
A
dditional
R

A
gent)-(CH)
x have been synthesized at room temperature. “New”-(CH)
x is formed by polymerizing acetylene on flat polymeric or glass substrates using an AlEt
3/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 I
2/CCl
4 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.
