Abstract of corresponding document: US4496702
The present invention relates to coherent poly(acetylene) films and to
a method of producing such polyacetylenes. The process comprises
solvent casting a solution of a polymer of the general formula (V)
derived from a precursor (IV), and transforming the pre-cast, polymer
(V) into a poly(acetylene) (III) film and a by-product (VI) at a
temperature between 20 DEG and 200 DEG C. at reduced pressure. The
poly(acetylene) thus formed has a substantially higher density than the
poly(acetylene) polymers produced hitherto. The morphology of the
poly(acetylene) produced is that of a thin, coherent solid film with no
voids and, no basic structural units are visible even at a
magnification of 10,000 times. The polymers also have a lower
crystallinity than those produced by conventional methods.
