Abstract
Abstract Electrically conducting doped poly(paraphenylene) compositions, and process of making such compositions, having direct current conductivities of at least 10-3 ohm-1 cm-1, at room temperature, and up to 100 ohm1cm-1 and above; especially wherein the doping agent is a Group IA metal arene, a Group V halide, chlorine, bromine, or a mixture thereof; in particular potassium naphthalene, sodium naphthalene, AsF5, chlorine, or a mixture thereof. The polymers are useful as electronic devices, as substrates for electroplating, as materials for absorption of solar and of radio frequency radiation, and in general wherever electrical conductivity of the metallic type or of the semiconductor type, and light weight, are desired.
