A robust model of dilute polyelectrolyte solutions is constructed based on kinetic theory arguments. The polyelectrolyte molecules are modelled by finitely elongated non-linear elastic dumbbells with beads carrying identical effective charges. The electric interaction between the beads is described in a simplified way through an electrostatic Coulomb force. With two pre-averaging approximations, the constitutive equations of the fluid model are formulated in closed form; and its rheological… Expand

Computer simulations of diffusion and dynamics of short-chain polyelectrolytes.
TLDR
Brownian dynamics simulations are conducted to investigate the diffusional and dynamic properties of polyelectrolytes in dilute salt-free solutions and find that the dependence of the long-time chain diffusivity on the Coulomb interaction strength is very different from that of the Kirkwood short-time Diffusivity.
