Chlorination of polyacetylene

In fact, the mediator, i.e. t-BuOH, is electrochemically reduced to the t-BuO anion that nucleophilically attacks PVDF, in much the same way as potassium tert-butylate, to yield elimination products. The authors also studied electrochemical dehydrochlorination of oriented poly(l,2-dichloro-ethylene) films under heterogeneous conditions [9]. The starting polymer was produced by chlorination of polyacetylene [10,20]. The elimination product, however, was found to be predominantly polychlorovinylene with a small proportion of carbynoid moieties. The authors came to that conclusion because of very low intensity of the IR absorption peak attributable to triple C=C-bonds. On the other hand, its low frequency at 2145 cm could... 

Akagi, K. Kadokura, T. Shirakawa, H. Stereospecific chlorination of polyacetylene by chemical doping. Polymer 1992, 55(19), 4058-4065. 

A recent study related to the current topic concerns the chlorination of polyacetylene, and addresses a new aspect of chemical doping. Akagi et al. [157] show that iodine doping of stretched polyacetylene films followed by chlorination produces stereoregularly chlorinated...
