We report the concentration and temperature dependencies of the diffusion coefficients obtained from dynamic light-scattering studies for the poly ( y-benzyl a, 1-glutamate) -benzyl alcohol (PBLG-BA) system. These studies were made at dilute and semidilute polymer concentrations, mainly in the isotr

The gelation and gel-melting phenomena in semidilute isotropic solutions of poly(y-benzyl-L-glutamate) (PBLG) in benzyl alcohol were studied by small-angle neutron scattering measurements, using a deuterated solvent, and by cryotransmission electron microscopy. The reversible gels are formed when th
## Quasielastic neutron scattering has been used to study the motion of protons in two solutions of poly(y-benzyl L-glutamate) (PBLG) and deuterated benzyl alcohol (DBA) as they are brought from the high temperature (cholesteric and isotropic) phase towards the gel. Quasielastic neutron scattering
## Abstract The aggregation of poly(γ‐benzyl L‐glutamate) has been studied by measuring the specific Kerr constants (__B__/__c__) over a tenfold range of concentration and the intrinsic viscosities of solutions of a low molecular weight sample of the polymer in four solvent mixtures, viz., benzene–
A series of poly(cg1utamic acid) esters have been synthesized and studied by optical rotatory dispersion, x-ray diffraction, and infrared spectrometry. The results obtained emphasize the importance of the outer portions of the side chains in determining both the stability and precise conformation of
## Abstract The coil‐to‐helix transition temperatures of hydrogen bearing and deuterated poly(γ‐benzyl‐L‐glutamate) in 1,3‐dichlorotetrafluoroacetone/H~2~O and/D~2~O mixtures, respectively, have been determined. Together with previously obtained data for the conformational transition of this polype
