Adams, P.N., Monkman, A.P. & Apperley, D.C. (1993). A comparison of the molecular weights of polyaniline samples obtained from gel permeation chromatography and solid-state nitrogen - 15 nuclear magnetic resonance spectroscopy. Synthetic Metals 55(1): 725-730.

Author(s) from Durham


Polyaniline samples of different molecular weights were prepared using aniline enriched with 15N. Molecular weights were determined by gel permeation chromatography. 15N NMR spectroscopy confirmed that both samples were in the emeraldine oxidation state, and end group analysis techniques were used to compare molecular weights derived from G.P.C. with those from the NMR data.
