## Abstract The thermal helix–coil transition of four samples of poly(γ‐benzyl‐L‐glutamate) in the dioxane–dichloroacetic acid (DCA) mixture was studied by optical rotatory dispersion method. The transition occurred at very high DCA content (97.5% by weight) in this system. The transition parameter

The folding of randomly coiled poly(bg1utamic acid) to the helical state has been studied in N-methylacetamide by titration methods. Since this solvent would be expected to form amide-peptide group hydrogen bonds with the unfolded form of the polymer, to a first approximation no helix stabilization
## Abstract Dielectric dispersion measurements on poly‐γ‐benzyl‐L‐glutamate (PBLG) in dioxane and dioxane–dichloroacetic acid (DCA) mixtures in the frequency range 200 Hz–2 MHz were made in order to study the structure of molecular aggregates. The structure of aggregates is explained on the basis o
## Abstract A polarimetric electric‐field‐jump relaxation apparatus is described and used to determine the relaxation spectrum for the helix–coil transition of poly(α,L‐glutamic acid) in water at 24°C. A maximum relaxation time of 1.7 μc occurs at the transition midpoint (pH = 5.9) yielding a rate
