The mechanical properties of high molecular weight (similar to 130 000
Daltons) emeraldine base have been investigated as a function of
elongation. The tensile strength is found to increase by almost one
order of magnitude for samples stretched to 500% elongation compared to
as-cast samples. The behaviour of breaking strain and Young modulus is
essentially independent of elongation above similar to 300%. This
behaviour has been interpreted in terms of crystalline fraction, as
evaluated from X-ray diffraction measurements.
