ABSTRACT:
Compositions based on polythiophene are described having incorporated therein a polyether, such as polytetrahydrofuran. The polyether is present in an amount of at least about 10 weight percent of the polythiophene present. The compositions exhibit improved mechanical integrity, processing properties, and d.c. electrical conductivity over polythiophene. A process for producing the compositions is also described in which a thiophene compound is electrochemically polymerized in the presence of a dissolved polyether.
