Effects of polydispersity, branching and chain stiffness on quasielastic light scattering

Abstract

Aspects of polarized coherent quasi-elastic scattering by dilute macromolecular solutions are discussed. Effects of polydispersity, branching and chain stiffness are considered, particularly in respect to the observable first cumulant of the dynamic structure factor and its dependence on the scattering angle. A combination of integrated and time-resolved scattering data yields the maximum information. © 1982 IUPAC
