    • 1H NMRs of soluble PPVs in the literature are rare. One example (also exhibiting the 2.9 ppm peak) is: Holmes, A.; Bradley, D. D.; Friend, R. H.; Kraft, A.; Burn, P.; Brown, A. (all of CDT, Cambridge, UK), US patent US 5,328,809, granted 12.6.94; priority 22.8.91, Figure 24.

    • note
    • The intensity of the signal around 2.9 ppm is not influenced by the degree of purification, and therefore the corresponding structure must be an integral part of the polymer. The amount of this defect is dependent on the type of polymer and the polymerization conditions.

    • The residual chlorine content of the polymers was determined by incineration and subsequent argentometric titration.

    • note
    • The estimated amount of these groups corresponds to the degree of polymerization (∼1000). Assuming that further end groups are negligible, the number of branches present is likely to be low.
