This book was released on 1991 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of cis-rich N-(CH)x and ARA-(CHA)x forms of B.A.S.F. polyacetylene involving elemental analysis of the pristine polymer and conductivities of the I2/CCl4 doped polymer are reported. Even though significant quantities of catalyst residue are present, the conductivity of the doped polymer is comparable to that of doped Shirakawa (CH)x. The synthesis of polyaniline in its fully oxidized, fully reduced and selected average intermediate oxidation states is described. The processing of polyaniline films and fibers by thermal stretching to give conductivities up to 100 S/cm is reported. Both doped and undoped polyaniline fibers have tensile strengths approaching those of commercial polymers.
