The interaction of poly(L-glutamic acid) with 3,6-dioxaoctamethylenediamine was studied by circular dichroism spectroscopy under different conditions. In aqueous solution at pH 5,6 and in aqueous 1,4-dioxane (30–50 vol.-%) at pH 7,3 the conformation of poly(L-glutamic acid) was completely changed from α-helical to random coil in the presence of an excess of the diamine.
