| Abstract: | The changes in the structural organization of solutions of N,N-dimethylhexadecylammonium salt of the polyamido acid based on 3,3’,4,4’-diphenyltetracarboxylic dianhydride and o-tolidine in a dimethylacetamide-dioxane mixed solvent during 24-h keeping at room temperature were studied by polarized light scattering. The stability of the salt solutions was studied as influenced by the composition of the mixed solvent, chemical nature of its components, and molecular weight of the polymer.__________Translated from Zhurnal Prikladnoi Khimii, Vol. 78, No. 3, 2005, pp. 474–478.Original Russian Text Copyright © 2005 by Kalinina, Silinskaya, Sklizkova, Kozhurnikova, Filippov, Kudryavtsev. |
