It is not clear to what extent and in what way the polymer structure influences the stability of the doped polymer with respect to oxidation etc. In this work the authors have prepared and doped a variety of novel aromatic and non-aromatic poly conjugated polymers. Poly(acrylonitrile) and poly(methylvinyl ketone), when reacted in solution with base, both cyclise via ring closure processes to form ladder polymers. The cyclisation process does not necessarily go to completion on each polymer chain so that the expected product could be likened to a multi-block copolymer of the cyclised and uncyclised forms. The work to date has found that polymers which have been cyclised to the extent of 50% yield electrical conductivities as high as 1. 35 multiplied by 10** minus **2 Scm** minus **1 in the case of Li** plus doped cyclised poly(methylvinyl ketone). Cyclised poly(acrylonitrile) had an electrical conductivity of 3. 13 multiplied by 10** minus **8 Scm** minus **1 under similar circumstances but reached 1. 1 multiplied by 10** minus **4 Scm** minus **1 when doped with C10//4** minus .
