Polymeric films fibrillar

Sodium-reduced polyacetylene was functionalized in two separate examples. In the first example (87), the doped polymer was used to initiate the polymerization of ethylene oxide from fibrillar films of polyacetylene (Figure 5.5). The product did not become appreciably soluble, and poly-... [Pg.285]

The Durham route allows the preparation of polyacetylene in the form of continuous uniform and featureless films, as opposed to the entangled fibrillar morphology obtained by the direct polymerization of acetylene. [Pg.954]

The liquid crystal polymerization method was modified to prepare a vertically aligned poly acetylene film [58]. As a result, a film with a very curious morphology was formed that was composed of two layers. The layer on the solvent side had a vertically oriented fibrillar structure, whereas the layer on the acetylene gas side had a randomly oriented one. The modified method is very promising for visualizing the polymer growth process and clearly demonstrates that PA chains grow in a liquid crystal solvent. [Pg.305]
