TITLE: POLYACETYLENE PRODUCTION
European Patent EP0124979
 B1

ABSTRACT:
Abstract not available for EP0124979
Abstract of corresponding document: US4564492
This invention relates to a process for producing an oriented,
crystalline poly(acetylene) (III) in film or fibrillar form by solvent
casting a film from a solution of a polymer of the general formula (V)
derived from a precursor monomer (IV), and transforming the pre-cast
film of polymer (V) under tension or in a stress field into the
poly(acetylene) (III). The transformation is carried out at a
temperature between 20 DEG and 200 DEG C. under reduced pressure over a
duration of between 1 and 100 hours in an atmosphere inert to the
precursor polymer (V) film and to the poly(acetylene) (III).
Poly(acetylenes) are conducting polymers and find use in solid state
batteries, field effect transistors and the like.
