Abstract
A pyrrole polymer membrane having electrical conductivity and liquid crystal properties in the same matrix. The starting pyrrole monomer derivative is illustrated by the formula ##STR1## where R.sub.1 and R.sub.2 are selected so that at least either of them is an electron attractive group. Methods of producing such membranes by a electropolymerization process and by a chemical oxidation process are described.
