Summary We have synthesized polyphenylenesulphides, using phenols, xylenes, sulphur and halogens as starting materials. The substituted and partly branched polyphenylenesulphides obtained have been doped with iodine (I2). The structures have been investigated by elemental analyses, IR, NMR and GPC. The electrical conductivities of these products were rather low in the region of 10−6–10−11 Scm−1. Higher conductivity values were observed for the polymers containing methoxy- or acetyl-substituents compared with those containing hydroxyl groups. It is suggested that this depends, at least partly, on the absence of hydrogen bonds between the sulphur atoms and the hydroxyl groups. As was expected molecular weight also had the effect of increasing the conductivity values observed.
