摘要：
Disordered and oriented films of polyacetylene-block-polynorbornene-block-polyacetylene (PA-PN-PA) with different block sizes are investigated by means of electron microscopy, X-ray analysis and polarized infrared spectroscopy. TEM micrographs of WF6 doped stretched films show a lamellar fine structure resulting from oriented domains of polyacetylene. Polynorbornene domains are observed, too. X-ray analyses show fibre patterns typical for crystalline domains in the oriented polymer, while disordered films only show diffraction rings characteristically for polynorbornene and polyacetylene.
