The molecular-weight dependence of the rms radius of gyration »R 2 g … 1/2 of poly(gbenzyl L-glutamate ) (PBLG) in helicogenic solvents shows negative and positive deviations from expectations for an intact and rigid a-helix in the higher and lower molecular-weight ranges, respectively. In order to

## Abstract The storage and loss shear moduli, __G__, and __G__˝, have been measured for solutions of three samples of poly‐γ‐benzyl‐L‐glutamate with molecular weights from 16 to 57 × 10^4^, by use of the Birnboim‐Schrag multiple‐lumped resonator. The frequency range was 106 to 6060 H~z~, the conce
Light-scattering measurements were performed for a number of poly-7-benzyl-Lglutamate (PBLG) samples in dimethylformamide (DMF) and in chloroform-formamide (C-F) a t 25°C. Osmotic pressure data for some of these polypeptide samples in DMF a t 37°C. were also determined. The scattering radii (S2)'/I
