Abstract

Thiophene ethers having relatively large side chains can be easily obtained by reacting 2-, 3-, 2,3-, 2,4- or 3,4-C.sub.1 -C.sub.3 -alkoxythiophenes in the presence of an acid catalyst with a compound containing an OH group. The novel thiophene ethers are suitable as monomers for electrically conducting polymers.
