Abstract
The molecular weight of polyaniline samples, obtained by fractionated thermal vacuum deposition of emeraldine base, was determined by cryosc opic method and the number of aniline units in the polymer chain was c alculated. It is demonstrated that the second polyaniline fraction has the maximum molecular weight corresponding to 16 monomer units. The m olecular weight determination is based on the data of X-ray photoelect ron spectroscopy and can be performed either with or without an allowa nce for the presence of water in deposited polyaniline fractions.
