Miscellaneous Central Vestibular Disorderser total conjugation or sulfur linkages between quinoline units are described. Polyquinolines containing biphenylene units either in the main chain or at the chain ends undergo crosslinking and chain extension reactions. The use of biphenylene end-capped oligomeric polyquinolines as matrix resins in graphite composites is discussed.

https://doi.org/10.1007/978-1-4471-3698-9dation (“doping”) is linked to a phase transition by which regions of high conductivity in a less conductive matrix are formed. Model compounds for poly(acetylene) and oxidized poly (acetylene) are discussed with regard to the explanation of the spectral features observed in the conducting polymer.
