Structural features of moderately concentrated polymer solutions with different rigidity of the molecular chain

Self-Organization and Morphological Characteristics of the Selenium Containing Nanostructures on the Base of Strong Polyacids

“…Isotropic parameters of structure such as average square of scattering micro-volume polarizability fluctuation <> 2 and radius of polarizability fluctuation correlations  V were determined from angle dependence V V ; the following isotropic parameters such as square of optical anisotropy average density <> 2 and radius of correlation of optical axes of scattering elements of volume  H . The parameters of isotropic structure are connected with dimensions  V of macro-molecules or associates and with micro-heterogeneity <> 2 as a function of density fluctuation [25,26]. Nature of dependence of the parameters of anisotropic structure on concentration allowed determining of system order and statistic dimensions of oriented regions.…”
