POLYACETYLENE PRODUCTION |
摘要 |
<p>Case 5247 Polyacetylene production 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 and 200.degree.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.</p> |
