Concentrated solutions and solid films of Poly-gamma-benzyl-L-glutamate were examined using proton magnetic resonance, X-ray diffraction and optical microscopy. The unusual findings can be correlated with the cholesteric-like liquid crystal phase known to exist in concentrated solutions of this polypeptide. The continuity in these observations on passing from the liquid to the solid state is interpreted in terms of the existence of a helicoidal structure in the solid state of PBLG derived from that found in the liquid crystal phase.
