Abstract
A process is described for producing partially crystalline polyacetylene in the cis or trans configurations utilizing.mu.-(.eta..sup.1 :.eta..sup.5 -cyclopentadienyl)-tris(.eta.-cyclopentadienyl)dititanium(Ti-Ti) catalyst. The resulting polyacetylene when 'doped' with halogen additives is useful as an electrical conductor or semiconductor. Also described are polyacetylene 'gels,' consisting essentially of a solid polyacetylene and gel-forming liquid therefor, also containing up to about 10 percent by weight of catalyst, per weight of acetylene, which is used for production of the polyacetylene. The gels are stable to phase separation at room temperature in a closed system, and are useful in preparing randomly and partially chain-aligned polyacetylene films and articles.
