Three samples of poly--phensyl-L-glutamate have been prepared from r-henzyl-,Vcarhoxy-L-glutamate anhydride with n-hexylamine initiation a t anhydride-to-initiator molar ratios, [A]/[I], of 3, 4, and 8, and their conformation and association in ethylene dichloride and dioxane have been investigated
## Abstract Reduced viscosity and infrared spectra of low‐molecular‐weight poly‐γ‐benzyl‐L‐glutamate (which was prepared by polymerization of the __N__‐carboxyanhydride with __n__‐hexylamine initiation at [A]/[I] 3, 4, and 8) have been measured in various organic solvents. Infrared spectra indicate
