A carbon chalcogenide macromolecular composition prepared from carbon dichalcogenide and to a process for the preparation thereof. A carbon dichalcogenide, for example, carbon disulfide, in entrained in an inert gas, and the mixture formed therefrom is passed over a hot tungsten filament wherein carbon disulfide is degraded into fragments. The fragments are then deposited onto a surface of a nonreactive substrate. The deposited fragments recombine to form the macromolecular composition. A significant characteristic of the composition is its threshold voltage above which its electrical resistance drops precipitously. This characteristic also exhibits a unique temperature dependence. Dopants may be added to the composition to reduce the electrical resistance.
