    • Virtually uncrosslinked polyacetylenes in film form are prepared by polymerization of acetylene using a liquid catalyst system consisting of an organicaluminum compound and a titanate in the form of a solution in a viscous inert liquid on a substrate to which the catalyst solution is applied, by a process in which, after the polymerization, the polymer is treated with a strong reducing agent which is inert to the organoaluminum catalyst component, the polymer is, if desired, oriented and is freed from residual catalyst and reducing agent by washing with a liquid, doped with a strong electron acceptor or electron donor in a conventional manner to increase the conductivity and dried, and the materials thus obtained are, if desired, covered with a layer or sheath of nonconductive material.
    • 膜形式的几乎未交联的聚乙炔通过使用由有机铝化合物和钛酸盐形成的液体催化剂体系的乙炔聚合制备,所述液体催化剂体系为溶液形式的溶液,所述液体催化剂体系是在施加有催化剂溶液的基材上的粘性惰性液体中, 其中聚合后聚合物用对有机铝催化剂组分是惰性的强还原剂处理,如果需要,聚合物是取向的,并通过用液体洗涤而被除去残余的催化剂和还原剂,掺杂 强电子受体或电子给体以常规方式增加导电性并干燥,如果需要,由此获得的材料被非导电材料层或鞘覆盖。
