Abstract
The soluble block copolymers of acetylene and isoprene produced by Aldissi1 using anionic polymerisation and Zeigler-Natta coupling catalysts show a strong dependence of electrical conductivity (after doping) on the volume fraction of polyacetylene.2 The threshold for this conductivity occurs at about 16% (v/v) and rises very steeply at higher concentrations. Preparations up to c 25% are soluble in toluene or hexane and have the property of retaining residual solvent when pumped to 10−3 τ at 300 K in a gel state. At 30% polyacetylene, the material is a hard solid which can be slightly swollen by solvent above room temperature and which is susceptible to iodine doping from the vapour.2Keywords
