Abstract:The effect of changes in chemical structure on the equilibrium and kinetic behavior is examined for fully cyclic poly(naphthoyleneimide benzimidazole) (PNI) molecules in dilute solution in 96% sulfuric acid. With this aim, hydrodynamic and dynamo-optical properties were analyzed over a wide range of molecular weight from 6.7 × 10 3 to 2.5 × 10. 5 The M dependence of the translational diffusion coefficient, D, the shear optical coefficient, ∆n/∆τ, the intrinsic orientation of the macromolecules in the flow, [ /… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
